Elliptic curve Diffie–Hellman[edit]

I've just moved Elliptic Curve Diffie-Hellman (with the incorrectly capitalized "C" and the hyphen where an endash should be) to Elliptic curve Diffie–Hellman. I've fixed the double redirects. Could others help fix the other redirects?

How did so many links get made to such a conspicuously incorrect title? Do people who work on cryptography articles generally disregard Wikipedia's conventions—even simple and basic ones like these? Michael Hardy (talk) 14:06, 23 October 2009 (UTC)

....and now I've spent a lot of time moving incorrectly titled cryptography articles. And fixing section headings in which Every Word Began With A Capital Letter. And fixing the resulting double redirects and bypassing some of the unprintable redirects to incorrect titles. The vast number of such links and the partial cleanups I've done in the past half-hour make it clear that civilized people will have to send missionaries to this WikiProject to inform its participants that WP:MOS and WP:MOSMATH and the like exist. Michael Hardy (talk) 14:25, 23 October 2009 (UTC)
....sigh....... I guess the fact that this WikiProject hardly exists won't make this easier either. Michael Hardy (talk) 14:26, 23 October 2009 (UTC)
+100 points for doing wiki cleanup. -100 points for pompously lecturing no-one in particular over picayune violations of the manual of style. You may find your exhortations more effective if you refrain from treating fellow editors as wayward children. — Matt Crypto 17:49, 23 October 2009 (UTC)
Part of that was directed at me it appears. Thank you Michael for making these changes and for your comments, I'll try to keep them in mind in the future. Cheers. Skippydo (talk) 02:55, 24 October 2009 (UTC)
Michael Hardy: Oh the rantings of the very young. :))
The convention to use endashes in article titles is brand new, up until recently Wikipedia used hyphens in article names. Most of these crypto articles were created years ago. And most of them use the naming that is established practice in the crypto literature.
That these articles are old is a good thing, we crypto editors were working hard and made many articles early in the history of Wikipedia. And this WikiProject was early on one of the bigger and more active projects. This project has become somewhat sleepy since it is hard to find more subjects to write about in cryptography, we already cover the area so well. Just doing maintenance and reverting edits by less knowledgeable editors is no fun in the long run, so many of our editors have gone to greener pastures.
Oh, and cryptography is not the same thing as math, all though maths people tend to believe so. Which usually becomes very funny (or very sad if you will) when maths people try to build "secure" systems...
--David Göthberg (talk) 05:08, 9 January 2010 (UTC)
Oh, the naivety of the romantics :)... Hard to find more subjects? Kidding me? Wikipedia is missing essentially everything that relates to more advanced cryptography, and all the "harder" articles that exist are poor stubs or start classes. And btw, cryptography is not at a stand-still, there are new important areas being created on and on. And cryptography is not math? Maybe up to the 19th century in the classical area, but nowadays real crypto is just maths and only maths. Only symmetric-key crypto has remained some of the art that classical crypto had but all its secure design approaches are based on mathematics as well. Just saying.

NSA Encryption Systems[edit]

The NSA Encryption Systems page has red/black reversed, at least according to the Red/Black Concepts page. Red is supposed to mean unencrypted and black means encrypted.

Book:Encryption[edit]

I feel the title is not the best one for this book (although I'm not entirely sure what exactly the book is about). Could someone give it a look? Headbomb {ταλκκοντριβς – WP Physics} 21:56, 8 January 2010 (UTC)

Haha, you've come to the right place. I took a look. Well, there are encryption, decryption, hashing, MACing, signing, cryptanalysis and many other related concepts and methods. They all are "cryptography", and that is why this is WikiProject Cryptography. So I suggest that book should be renamed to "Book:Cryptography".
--David Göthberg (talk) 04:36, 9 January 2010 (UTC)
What I'm saying is that book seems to be focused on a subsection of cryptography. So if it's renamed Book:Cryptography, it should probably be expanded. If not, then it should probably be renamed to something more focused (like Book:DVD encryption algorithms, or whatever makes sense). Headbomb {ταλκκοντριβς – WP Physics} 05:11, 9 January 2010 (UTC)
It's not much of a book, since it only has four articles. But anyway: Two of those articles are about hashing so just calling it "encryption algorithms" wouldn't work that well, and it has no article specific to DVD encryption so I don't know why you suggest using "DVD" in the title. But yeah, since it is a very basic collection of articles, then using the generic name "Book:Cryptography" would be bad, since that would block that name for better collections. How about calling it "Book:Crypto introduction". Of course, if it were a real introduction it should contain the Cryptography article. But shouldn't you ask the user that created that book to choose the new name?
--David Göthberg (talk) 07:09, 9 January 2010 (UTC)
The user is inactive (last thing he did was create the book). My suggestion was an example of a more speciffic name, I know nothing of encryption (hence why I said "or whatever makes sense"). There's the 'Standard 4' subtitle, do you know what that refers to? Headbomb {ταλκκοντριβς – WP Physics} 08:09, 9 January 2010 (UTC)
The "Standard 4" subtitle almost certainly refers to the four articles in that book. Three of them are very much the three basic areas in cryptography. While the article Hash function is not, it's just an introduction that might be good to read before Cryptographic hash function.
--David Göthberg (talk) 08:50, 9 January 2010 (UTC)
What I mean is if I walk in a cryptography conference and say "the standard four", will people ask "What standard four?" or would they know I'm talking about these four topics? If they would know, then Book:Cryptography: The Standard Four is a good title. If they don't, then it's a bad title. Headbomb {ταλκκοντριβς – WP Physics} 17:11, 9 January 2010 (UTC)
No, they wouldn't know what you meant with that expression.

Missing cryptography topics[edit]

Can anybody have a look at this list of missing cryptography topics - Skysmith (talk) 12:12, 8 April 2010 (UTC)

Weak security categories[edit]

WP should have a couple categories to identify weak and broken crypto. I think articles such as WEP, Crypt_(Unix), md5, Enigma and Cryptoloop should be in something like Category:Broken cryptography for algorithms and software that have serious design or implementation flaws (not of the rubber-hose cryptanalysis type). I think articles such as Adobe Flash, and Little Snitch should be in something like Category:Insecurely distributed software for software distributed only via insecure methods, such as over ftp or http, without PKI-based signatures or securely distributed secure checksums, or without tamper-resistant retail packaging. (The related Category:Securely distributed software is probably also appropriate, e.g. for software like LastPass and the Linux Kernel; the latter get credit for defense in depth; the stuff is served over https, and is PGP-signed.) Thought I'd post here for any feedback before getting started on making it so; we could mention this at Wikipedia talk:Categorization. Notes: These would NOT be for indicating software with remedied or un- remedied exploits. Besides, those are too transient to be practical (unless the flaws go uncorrected for a long time), or too unimportant to be encyclopedic. (Categories need parents; will need to take care of that.... Oh, Category:Broken cryptography algorithms ∃. ) --Elvey (talk) 04:27, 23 October 2010 (UTC)

I have a question. Would articles placed in either Category:Broken cryptography or Category:Insecurely distributed software unequivocally belong in those categories? I.e. would there be reliable sources that presented unambiguous conditions for labeling a piece of software as one or the other? Also, if this requirement is met I would expect to find these matters discussed in sections of some of our existing categories or even in dedicated articles. __meco (talk) 07:57, 25 October 2010 (UTC)
I'm also concerned about verifiability. It's hard to track category usage (you can't watch a category for added articles), so people will slap them on articles based on personal belief, not verifiable sources. There's also no way to add a citation for a category.
Also note that these days, almost everyone recognizes "crypt (Unix)" to be the shadow password hashing technique, which is still secure today. The "crypt" encryption command was never present on modern unices. So the article should be split first, but I'm not sure that the encryption program can even pass notability. -- intgr [talk] 08:31, 25 October 2010 (UTC)
I don't know that it's a useful idea. We already have Category:Broken block ciphers, and any published certificational weakness is enough to put an algorithm there. Ntsimp (talk) 14:55, 25 October 2010 (UTC)


Thanks for the comments. I see that WEP and md5 are appropriately categorized now. Certainly, membership in Category:Securely distributed software is readily verifiable; the source is considered reliable for such info, as a company is considered a reliable source for its financials and such. Membership in Category:Insecurely distributed software often can't be firmly established; I'll search further to see if I can find an RS I haven't heard of. I disagree; crypt is several things, it's common to have it refer to any of an insecure encryption system, an insecure password hashing system, a secure encryption system, or a secure password hashing system.
What you are suggesting seems too close to WP:original research. Looking at how a product is distributed and concluding the method is insecure would be an improper synthesis. In general, using category assignments to make editorial comments is bad for a number of reasons.--agr (talk) 21:47, 16 April 2012 (UTC)

Making binary human-readable/pronounceable for cryptographic, similar purposes[edit]

Hi. In the course of considering the Bubble Babble article, we/I came to the realization that it might be useful to merge it and some other articles on algorithms into one article on transforming binary into something human-readable/pronounceable, either via generating pseudowords/logatomes (like Bubble Babble) or into series of actual words (like the PGP word list, Diceware, and S/KEY). Any thoughts? What other algorithms exist and should be in such an article? What's the proper name for such an article? Thanks very much! Allens (talk) 01:02, 1 November 2011 (UTC)

There is an article Human-readable medium which seems to fit this. I think the secondary name in the article Human-readable format is better. I'd say Base64 and hexadecimal fit this, but that's arguable as it would still be cryptic to most people. Maybe include these towards one end of a spectrum. --Flexdream (talk) 18:50, 8 March 2012 (UTC)

Template:WikiProject Cryptography and assessments[edit]

Any particular reason why Template:WikiProject Cryptography does not support assessments? --Piotr Konieczny aka Prokonsul Piotrus| talk to me 02:53, 9 February 2012 (UTC)

No, I think the template was just never updated when assessment grades were introduced. Can you do that? It would be great if the template could be extended to support assessments, I just never got to check what needs to be done to support it. Nageh (talk) 17:08, 9 February 2012 (UTC)
I cannot, but if you ask on WP:VPT, I am sure somebody will help you out. --Piotr Konieczny aka Prokonsul Piotrus| talk to me 22:29, 9 February 2012 (UTC)

Random function[edit]

Please consider article random function. Presently it contains cryptography-based stuff, that seems very unclear and uncited. It seems to be using the term in a way that partly conflicts with what would be wanted for a more general article in the context of probability theory or statistics. A question is whether what is in the article does actually reflect usage in cryptography and whether it would be better dealt with under someother establisahed terminology. But a clean-up to raise the article from stub status would be good in any case. Melcombe (talk) 17:12, 28 February 2012 (UTC)

Essentially, the definition is in the first two to three sentences, and this is independent of any crypto stuff. The concept of random functions is quite important in provable cryptography, so this is quite relevant to the article. In its current state, it is really weak, though. I will see when I get to work on it. Nageh (talk) 21:58, 28 February 2012 (UTC)
Thanks. I suppose I was most concerned with the "finite set of functions" mentioned as possibilities early on, which is limiting. Melcombe (talk) 23:37, 28 February 2012 (UTC)
Well, right. Cryptography is only concerned with discrete random variables, and I cannot think of a practical case where the sample space for random functions would be infinite (usually, they are selected uniformly at random). Maybe you can add a formal, general definition of a random function? I can then work on its application in cryptography. Btw, what is the purpose of the hatnote you added? It doesn't seem to me that anyone looking up "Random function" would really be looking for "Random number generation". Nageh (talk) 02:04, 29 February 2012 (UTC)
I did a quick Google on "random function" and essentially all of at least the first few pages returned items about subroutines (usually implemented in the form of "functions") for generating random numbers. Hence it seemed that this might be a common term for someone starting from computer programming. Melcombe (talk) 11:15, 29 February 2012 (UTC)
Hm, I didn't think of that. Makes sense. Nageh (talk) 12:15, 29 February 2012 (UTC)
I have now expanded the content for more generality, and added projerct banners on the talk page. Feel free to change anything. Melcombe (talk) 12:17, 29 February 2012 (UTC)
Thanks! Nageh (talk) 12:59, 29 February 2012 (UTC)

When is a cryptographic algorithm notable?[edit]

Let's see how alive this WikiProject is. I am currently going through a list of cryptography articles in my attempt to rate them with quality and importance asssessments. What I have found is that there are a few articles on cryptographic algorithms whose notability is highly questionable. As an example, here are three block cipher algorithms that all seem to be based on the same principle and which seem to be based on two main authors, Nikolay Moldovyan and Alexander Moldovyan: Cobra ciphers, CIKS-1, and Spectr-H64. The basic principle of the algorithms is that of "data-dependent permutations", which is based on the more general principle of data-dependent operations (e.g., rotations, key scheduling, etc.), which really isn't that new. The concept is suggested to develop faster ciphers.

The problem now is threefold:

  1. For each of above algorithm, there seem to be just three independent papers, each of which shows that the design is insecureless secure than claimed. There seems to be no further indication for notability. In particular, it is missing the significant coverage by reliable independent sources as expected per our notability guideline.
  2. The concept of data-dependent permutations is just a specific case of data-dependent operations, which are nothing new in cryptography or block cipher design, either. In particular, data-dependent rotations have been used in the RC5 cipher, and key-dependent mixing functions are used in several existing ciphers. There seems to be no indication that the specific concept of "data-dependent permutations" in block ciphers is notable in the sense that it warrants its own article (if it were, the simple solution would be to merge the material into an article on that concept).
  3. New suggested cryptographic algorithms are like a dime a dozen (and the WikiProject's template on block ciphers is somewhat a testimony to this). Most of them quickly fall into oblivion either for being superseded by better designs building on the suggestion or for being shown insecure.

So the question is: Does a publication in a journal automatically warrant notability? (My opinion: Getting something published is not a high barrier, and this alone is certainly insufficient.) Does the existence of a few papers by independent authors, showing that the design is insecure, warrant notability? (My opinion: If the fact that a design was insecure were so surprising then it certainly would be discussed more widely. Otherwise, it is not enough to indicate notability.) And does the existence of better designs, which refer to the original design, justify inclusion on Wikipedia? (My opinion: If the original design was truly "original" it would be highly cited, thus proving notability. Otherwise, it may warrant a mention in a more general Wikipedia article, but not as a stand-alone article.)

I'd be interested in your thoughts on this. If I don't get any response, I'll bring the three articles to AfD. Cheers, and many thanks, Nageh (talk) 17:52, 12 April 2012 (UTC)

If the total contribution to scholarship with regard to some piece of cryptography is simply a proposal followed by a total break, it is very likely that the topic is not notable. Skippydo (talk) 18:33, 12 April 2012 (UTC)
Yeah, sure. The algorithms are not completely broken, but they are clearly flawed (i.e., immediately shown less secure than claimed) as outlined by the independent papers. That doesn't seem to be any indication for notability to me, though. Nageh (talk) 18:58, 12 April 2012 (UTC)
"Does a publication in a journal automatically warrant notability?" No, pre-publication peer review is too weak to establish notability, you need independent citations to establish notability. "Does the existence of a few papers by independent authors, showing that the design is insecure, warrant notability?" No, this merely indicates the contributions failed post-publication peer review. I assume this to be a common phenomena in the field of cryptography. The obvious exception would be if the contribution becomes a text book example of how not to design a cryptographic algorithm or protocol. "And does the existence of better designs, which refer to the original design, justify inclusion on Wikipedia?" This would depend on the exact amount of independent references, I guess. —Ruud 19:10, 12 April 2012 (UTC)
Thanks. I think we are in agreement. Nageh (talk) 19:34, 12 April 2012 (UTC)
I'm surprised at the notion that "three independent papers each" doesn't constitute significant coverage by reliable independent sources. We're not talking about DES here, but notability is all about the sources, and there they are. So what if the papers are breaks of the ciphers? That's still significant coverage. Few ciphers are as notable as the totally-broken FEAL. It seems like you're saying that only groundbreaking new cryptographic ideas that stand the test of time warrant Wikipedia articles. That's a much stricter standard than notability, and I don't support it. But I will defer to whatever consensus develops. Ntsimp (talk) 20:47, 12 April 2012 (UTC)
No, that's absolutely not what I am saying. Have a look at Category:Block ciphers. There are 107 ciphers listed, and most of them satisfy the "significant coverage" requirement of WP:N. The three ciphers discussed here do not. I think it should be obvious that publishing a cryptographic algorithm only to have it broken by other researchers, without any other coverage of the algorithm, does not count as being notable. If you think that is a criteria for inclusion, have a look at this list of pairing-based cryptography algorithms, as an example. An argument could be made that each of these cryptographic algorithms should have an article on Wikipedia, simply because it is being listed there. However, in the case of the three ciphers discussed, absolutely no other secondary coverage could be found. Assume further that in addition to this list of algorithms there have been many more proposals published in journals that have quickly been either shown insecure (by other researchers) or been superseded by better solutions (by other researchers) – without any other secondary coverage, do you think this alone warrants sufficient notability for inclusion on Wikipedia? My answer is a strong and capitalized NO. From WP:NOT: "[Wikipedia is not] a scientific journal." And I'm pretty inclusionist in this regard. To the best of my knowledge, and I really did try hard studying both the primary papers and secondary literature on these algorithms for indication of sufficient notability, but I don't see them as being suitable for inclusion. Nonetheless, a sincere thank you for your feedback! Nageh (talk) 21:13, 12 April 2012 (UTC)
PS: I checked the citation indices of the relevant papers. It appears that after subtracting self-references, then apart from references by two (not three, actually) independent author teams describing attacks on the system there is only ONE reference left by other independent authors to a single paper, namely a reference to "A cipher based on data-dependent permutations" (2002) from the paper "ARMADILLO: a Multi-Purpose Cryptographic Primitive Dedicated to Hardware". Notability looks different, if you're asking me. Nageh (talk) 21:33, 12 April 2012 (UTC)

Ok, I have found where these articles could be redirected to. An article on lightweight cryptography. Unfortunately, it has to be created first. :/ Nageh (talk) 20:04, 13 April 2012 (UTC)

Rationale for including functions in the hash function template[edit]

What is the rationale for including hash functions in the template?

Functions like FSB, ECOH, and SWIFFT were SHA-3 candidates but not very signicant ones; they did not pass to the second round. Why are they listed here when most second round candidates are not?

Same question for the list here: List_of_hash_functions#Cryptographic_hash_functions. That list also include Spectral Hash, a completely broken SHA-3 candidate.

On a related note, many second round candidates do not have a Wikipedia page, even though they are much more significant than Spectral Hash...

Ni fr (talk) 12:57, 18 April 2013 (UTC)

I don't think there is a "rationale", someone probably just added those hashes to the template without much thought. It certainly shouldn't try to list every cryptographic hash under the sun. Be bold and remove them.
As for the list article, I think it makes sense to include every hash function we have an article about. Whether Spectral Hash warrants an article is another question -- probably not per notability (there are no secondary sources).
The solution certainly isn't creating more articles of questionable notability. -- intgr [talk] 18:01, 18 April 2013 (UTC)

RfC concerning the Lavabit email service[edit]

There is a request for comments (RfC) that may be of interest. The RfC is at

Talk:Lavabit#RfC: Should information about Lavabit complying with previous search warrants be included?

At issue is whether we should delete or keep the following text in the Lavabit article:

Before the Snowden incident, Lavabit had complied with previous search warrants. For example, on June 10, 2013, a search warrant was executed against Lavabit user Joey006@lavabit.com for alleged possession of child pornography.

Your input on this question would be very much welcome. --Guy Macon (talk) 05:07, 29 August 2013 (UTC)

Implementations in source code[edit]

Should more of the articles have simple implementations in source code? A good example is the md5 article which has the implementation in pseudocode as well as the C programing language. Thea10 (talk) 16:23, 13 September 2013 (UTC)

Unfortunately, dozens of programming languages have their own programming language partisans that feel they need to "promote" their favorite programming language wherever possible. People who are not programming language partisans generally feel that including an implementation in every one of those languages in a single article is excessive. (Wikipedia talk:WikiProject Computer science/Manual of style#Concrete Implementations of Algorithms; Wikipedia talk:Algorithms on Wikipedia/More talk).

Rather than put source code directly into the Wikipedia article, perhaps it is better to put that source code into Wikibooks: Cryptography, or into a wiki dedicated to source code such as http://rosettacode.org/ (In particular, see http://rosettacode.org/wiki/MD5/Implementation ), http://en.literateprograms.org/ , http://codesnippets.wikia.com , or etc., or into some other source code repository website. Then add a (indirect) link into the Wikipedia article pointing at that off-site source code.

Alas, some people think that merely *linking* to implementations in many languages is excessive (Wikipedia talk:WikiProject Computer science/Archive 10#External links to implementations). --DavidCary (talk) 06:36, 4 February 2014 (UTC)

Entropy Page In Need of Review[edit]

I noticed today that the Entropy(Computing) Page has been marked as in need of an expert reviewer since 2009. Is there anyone in this project that might be up to the task? I read the entire page and think it sounds pretty good. Then again, I'm a chemist, and not a cryptographer or computer security expert. With the recent comments of L.

Discussion at Template_talk:WikiLeaks[edit]

You are invited to join the discussion at Template_talk:WikiLeaks. Neutral assistance requested. At issue is whether the template for wikileaks should show "Chelsea Manning" or "Chelsea (formerly Bradley) Manning" or some other formulation. Obi-Wan Kenobi (talk) 00:56, 25 October 2013 (UTC)

Assassination market article - anyone want to help?[edit]

After the in-depth Forbes article on the Bitcoin/Tor-based Assassination Market website, this article (about the general concept of an assassination market, not the Internet specifically implementation) is looking a bit out of date.

If it's within the remit of this project, anyone want to help out with updating it? Jonathan Deamer (talk) 21:04, 9 December 2013 (UTC)

Invitation to help craft a proposal[edit]

Surveillance awareness day is a proposal for the English Wikipedia to take special steps to promote awareness of global surveillance on February 11, 2014. That date is chosen to coincide with similar actions being taken by organizations such as Mozilla, Reddit, and the Electronic Frontier Foundation.

Feedback from members of this Wikiproject would be greatly appreciated. Please come join us as we brainstorm, polish, and present this proposal to the Wikipedia Community. --HectorMoffet (talk) 11:21, 18 January 2014 (UTC)

"Numerical cipher"[edit]

A recently created redirect, Numerical cipher (edit | talk | history | protect | delete | links | watch | logs | views), currently points to Bifid cipher, is this correct? -- 70.50.151.11 (talk) 10:15, 23 February 2014 (UTC)

Kama Sutra Cipher article vastly inaccurate[edit]

The Kama Sutra doesn't have a 45th chapter. The Kama Sutra instead describes cryptography as a recommendation for pleasurable activities to be pursued by women. I believe it is actually number 44 on the list. It's easy enough to find in the translation in Project Gutenberg by searching for the word "cypher." There are a lot of places that repeat this misinformation, possibly because it's on Wikipedia.

One source I've found, The Six Unsolved Ciphers, seems to have a bit better of a description, and is consistent with further academic sources I've found. Note that I've found academic sources that cited the incorrect Wikipedia article (why would you do that?). The words to look for are Muladeviya and Kautilyam.

The best source I've found thus far: Novel Cipher Technique Using Substitution Method, Shobha Vatsa, Tanmeya Mohan, A. K. Vatsa, International Journal of Information & Network Security (IJINS), Vol.1, No.4, October 2012, pp. 313~320, ISSN: 2089-3299

Page 317 touches on the Kama Sutra cipher, and describes what is shown in the Wikipedia as Muladeviya. The wording around it is a bit difficult to parse though. It references a research paper "presented as Aryabhata's Mathematics," and that Yasodhara described this cipher along with Kautiliyam (substitutions based on phonetic relations).

Unfortunately the citation for that section looks like this: http:// Aryabhata‟s Mathematics by Subhash Kak, RSA Conference, San Jose, Feb. 13-17, 2006

Please pardon my formatting, I haven't edited Wikipedia before aside for minor spelling corrections. — Preceding unsigned comment added by 132.198.220.151 (talk) 14:40, 17 June 2014 (UTC)

User:Tango_Mike_Bravo/Walsh_Report_(cryptography)[edit]

I have drafted an article on the Walsh Report more correctly titled Review of Policy relating to Encryption Technologies that was conducted for the Australian government in 1996. Having been a board member of Electronic Frontiers Australia who played a major role in the Walsh Report I have a potential conflict of interest in this article.

Could one or more editors here please review my draft, edit it if you want to, and—if you then consider it sufficiently neutral and meeting other criteria for Wikipedia articles—move it to mainspace. Tango Mike Bravo (talk) 08:44, 23 August 2014 (UTC)

Thanks to User:Graeme Bartlett this has now been moved to mainspace. Tango Mike Bravo (talk) 11:32, 15 September 2014 (UTC)

Comment on the WikiProject X proposal[edit]

Hello there! As you may already know, most WikiProjects here on Wikipedia struggle to stay active after they've been founded. I believe there is a lot of potential for WikiProjects to facilitate collaboration across subject areas, so I have submitted a grant proposal with the Wikimedia Foundation for the "WikiProject X" project. WikiProject X will study what makes WikiProjects succeed in retaining editors and then design a prototype WikiProject system that will recruit contributors to WikiProjects and help them run effectively. Please review the proposal here and leave feedback. If you have any questions, you can ask on the proposal page or leave a message on my talk page. Thank you for your time! (Also, sorry about the posting mistake earlier. If someone already moved my message to the talk page, feel free to remove this posting.) Harej (talk) 22:47, 1 October 2014 (UTC)
