Back to following this after a several-year hiatus; haven't got my admin-fu turned back on yet, but it doesn't look like it's needed. I do have a certain experience with wikis for webcomics, as for example for Errant Story, the one and only webcomic I know of that's as interesting as this one. Check its wiki, the Heretic Knowledge Vault, for a sense of my approach to wiki-ing; the FAQ section there was written mainly by me (as was a lot of other stuff).
I'll help here when I can, although I'm a working stiff with other things to do. (Update: no longer a working stiff. Retirement is a wonderful thing. But still with other things to do.) I'm very happy to have found this wiki -- if there was ever a webcomic that needs one, GG is that webcomic.
BTW, check my Sandbox (or, if you prefer, Laboratory) page to see what mad projects I'm working on before they're ready to go public in the main pages.
