I am a serious shell collector, and a former Ph.D. student in Marine Biology from Florida State University (until I changed career paths and became a lawyer) and member of the San Diego Shell Club. I maintain a keen interest in the science and was most pleased to finally see mDNA testing (and now some nuclear DNA testing as well) of large monogeneric families. I live in Orange County, California. I try to keep up to date with the latest systematics for my personal shell collection, comprising over 175 families of molluscs.

After over 20 years of fine tuning the programming I have finally competed to my satisfaction a Shell Collection Database Management Program which incorporates the latest systematics to keep records in systematic order, add digital macro pictures, print data tags and reports. The program is now being offered for sale on a select website,[[1]].

I have placed a number of my macro shell photos from my Shell Collection Database Management Program on Wikicommons and attached them to the Wikipedia articles listed below.

I have been a Wikipedia editor for several years now, with a focus on the taxonomic issues in the Conidae. I am also trying to add many more quality macro photos of molluscs to Wikipedia. Recently I became co-editor of The Festivus, which is now a quarterly publication on malacology and conchology.

Special thanks to Invertzoo for welcoming me and for inviting me to join WikiProject Gastropods, and for Invertzoo and other senior editors including Ganeshk and JoJan helping "teach me the ropes" as well as for their welcome mentoring and encouragement.

A fascinating "new" species of Nudibranch - Why dream up aliens from space when we have real life animals like this?
A Barnstar!

A very big WELCOME to WikiProject Gastropods for you Shellnut, a new member! We are delighted that you decided to join the Project! Thank you for your interest and I hope we will have a fruitful collaboration. Wikipedia is tough to find your way around at first but it does get easier. If you start out with small easy edits on article like copyediting, then gradually work your way up to bigger things, that's a good way to go. Best wishes Invertzoo (talk) 00:19, 2 October 2011 (UTC)
A Barnstar!

A big Welcome to WikiProject Bivalves for you, Shellnut, a new member! We are delighted that you decided to join the Bivalves Project; we can really benefit from having someone around who knows the up-to-date taxonomy. Thank you and welcome, Invertzoo (talk) 14:40, 3 January 2012 (UTC)

Tokens and Tools[edit]

TUSC token 19d247d9850d895ebee7870b3cf04b99
I am now proud owner of a TUSC account! A useful tool for finding free images on the internet (especially FlickR), suited for the Commons : FIST ([2]); special thanks to JoJan!

Simplified instructions, per JoJan:
1. "You tick the box with "articles", instead of "Categories or articles".
2. The number of results in FLickR: I usually change that to 95. The other databases give sometimes also a result.
3. Below in "List" : tick the box in "All articles" instead of "Articles that have no image".
4. Fill in your TUSC password and your Commons user name. Click on 'Do it !'."
