He was one of the original members of the crew from way back at SitePower (the very first version of this place that predated even the EZBoard), and then he hung around on the EZBoard for, oh, two years I think. He left a little before the hack that wiped the EZBoard the first time, and he wasn't even around for when ICVDF (at that time called the Bootleg Dungeon) split off and formed their own group...
He was just a fun, laid back dude. One of those guys you chat on a forum with for hours. I think most of the really old Dungeonites probably hung out with Jimmer on the forum or AIM on the regular. When he left we were all sad.
