JD:
Scratch me from the list as I probably didn't post until 1999 (deleted my account @ some point and then reinstated it maybe in 2000).
I recall (though my memory of A'Gon originally being a male nurse chatroom may be incorrect;-) other names...
-David99 (a pioneer running 805's with, @ some point, an Aleph 30).
-Kublakahn (love me some Dennis).
-Sam from NYC (always attempting to properly power PSB Silver/Goldi's).
-Sedond with interesting gear @ the time (Audio Alchemy for example).
Think Cornfed/Kelly came a bit later, but his Scotch propelled alter ego late night Sluggo posts were both harmless & hilarious (a fine line to toe online).
I'm allowed to post anything @ A'Gon only because one of the staff has a cyber crush on me being that I'm rich, famous and extremely sexy in real life (she figured out who really I am).
