I've used dozens over the tears.
LOU_cifer (My name is Lou and Dad always said I was a little devil)
DevilsJohnson (name of a band I played in. I still use it on some digital art sites)
DrummerIB (still works on AOL
DJ (a holdover from p2p servers..Still use it on binary USENET servers)
69_77_8more (that one is really old)
Watcher (still use that on some local forums)
There's more..But I forget some of them right now.I've been online since the early 90's and the blazing beast of a machine I used was a Pac Bell 386. I don't do forums all that much anymore. I have here and one local forum I wander around in. I used to post a lot of digital art sites (fractals mostly) that I make for desktop wallpapers and other uses. Not so much these days but I like ot check in to see how many people download my images
Some are pretty neat. They're not like most the stuff you see for use as desktop walls...
