Oh, let's see...
Kelvrick - nice guy with a quick smile and easy laugh.
KEV1N - sharp enough to spot me out of a cafeteria full of college students, though we'd never met, and pick me out as an ATer.
JeremyJoe - laid back, nice guy.
ffmcobalt - funny, a talker, very energetic, quite nice.
eyecandy - very tolerant of ffmcobalt, smacks him down when needed, good-natured gal.
ViperGTS - one of the out and out neatest people there is. Very quiet, absolute SWEETHEART of a guy.
Orsorum (zakath15) - chatty, quirky, philisophical, likes to ask weird questions. Good listener with a lot to say.
Russ - cool, self-assured, pretty much everything he was on ATOT but less biting. Just as independent and crotchety though.
linuxboy - where do I start? Cheery.
Zenmervolt - one of my best friends. Very like he is online, an obvious softie, quick-witted, laughs easily, makes frequent mildly sarcastic responses.
I've met more but those are the ones that stand out.
