I am Doomhand, or the artist formally known as TheDude. As for the Wiki, I was a frequent contributor to Wikipedia for a few years until I realized that it's a load of garbage, though the Wiki system is great. I have contributed to various gaming and topical wikis, such as Star Wars, Resident Evil, Silent Hill, Elder Scrolls, LotR (books), and Thief: The Dark Wiki.
I highly recommend the Silent Hill, Star Wars, LotR, Elder Scrolls, and WoW (of course) wikis for their great atmosphere and helpful communities. I do not recommend the Thief wiki currently due to their problem with hit-and-run editors and their mass of speculation in articles, though this will hopefully be fixed and I encourage editors to help out.
