Hi there. I've been involved in Wikipedia, on and off, since before 2005, when I was a child. I've used IPs and other names in the past before opening this account. I'm based in South East England, but I've spent a big chunk of my life until about 2003 in Gauteng, South Africa; and until about 2009 in Greater London, UK.
Send things to me on my talk page. I'm very likely to see it.
You can send me a private message too. You can also say how I may use information you give in a private message (for example, whether or not it may be included in a Wiki talk page if it is Wikipedia related - I will assume not). Private messages are plaintext emails (and emails go through many servers owned by other people), don't expect secrecy by default.
I often make typos or mistakes in my edit summaries, and I don't bother correcting them. If you think some information in the edit summaries conflicts with reality, that's probably why. If you need any clarification, you can ask me directly, or look at the surrounding contributions for clues (i.e. talk page messages I've left).
I see Wikipedia as a public resource, an important contribution to the collective usefulness of the Internet, and something that helps the survival and progress of humanity, and will for many years to come, even if it gets replaced by something with a different name.
Wikipedia has constant issues regarding neutrality and reliability, but many different people from all over the world use it every day, life would be very different without it (likely replaced by something more authoritarian). I've taken much from Wikipedia, and applied it to many different things in life. I mostly pay back with my small contributions of information, and in the past I also gave money. I still use Wikipedia, and am likely to pay back for a long time.
I am primarily interested in computers, software & programming, Linux, networks, and suchlike. In fact, reading and editing Wikipedia played a key part in getting me interested in those fields. But I don't limit my editing to that area, and I typically edit articles I read (meaning, I typically edit about things I wanted to find out more about), and sometimes also random articles, articles on my Watchlist that I have edited before, and articles I find while using STiki.
I usually contribute with small corrections or adjustments on the articles I read, or through verifying that things match up with existing references, rather than adding new information. I also do the same to Commons images, usually vector images being used on Wikipedia. I typically don't have enough time to add new information, and issues like Wikipedia's interpretations of POV and Notability always appear to be an obstacle.
