I've been using the callsign Pyrite or Pyritefoolsgold on various forums and such since middle school.
I've done a little editing so far, but haven't seen an opportunity to start an article of my own yet.
I also believe that Wikipedia should have a more extensive set of articles on Webcomics, and frankly any webcomic that has a fair archive should get an entry, but that's just me, and I won't tear up the community about it.
A few webcomics that I would like to see articles made about:
captain SNES
Station V3
Hard Underbelly
The Chian Empire
Nine Planets Without Intelligent Life
A Taste of Evil
Dex Lives
Nerdcore: The core wars
Savvie and Lacey
Dementia of Magic
Of course, if I thought it wouldn't get deleted, I might just go ahead and make several of these. Wikipedia's definition for a Notable Webcomic has eluded me so far.
