Not a long list, but it was fun while it lasted. In roughly chronological order of when I started playing the character (and if you remember TarotMUCK, you have just impressed the hell out of me, because I haven't yet met stumbled across someone else online who was on any game in 1990).
TarotMUCK: Pixel
PernMUSH: Rian
CrystalMUSH: Deidre
CrystalMUSH: River
CrystalMUSH: Kira
Crystal Dreams: I honestly don't remember my character's name. Didn't last more than a month or two.
FiranMUX: Sholana
FiranMUX: Yandora
FiranMUX: Niva
FiranMUX: Isa
FiranMUX: (scattered random handful of characters who lasted for days at most)
A Snitch In Time: Hagrid
FiranMUX: Tarana
FiranMUX: Kelarik
FiranMUX: Talon
FiranMUX: Natan
In addition, I staffed on Firan from late 2000 to early 2002. (No, I didn't kill your character. Unless the shark ate it, that is; I built the shark. So if you got eaten by a coded shark, oops. And if you fed someone to the shark, shame on you. Sharky probably got indigestion from that.)
Still, epic good times, and we got to play with firebombs and blow up a bridge, so I still have to count that as a win. Glad yours was one of the couple who made it out from that whole insane mess!
