From my
crosspost at Final Fantasy Society, some other folks I knew or at least remember reading:
Tiara
Emerald Aeris
Timelord
Princess Usa (not U.S.A.) and her brother... I want to say Tera something... Teraphor? It wasn't Terrapin.
Edge (He did something with the capitalization... eDgE? EdGe?)
Kain
clOuD
Arvynia
Pixie
Rinoa (There were many of them of course... but she a member of our goup. I forget other names she used.)
Never Is A Promise
Lilly Rinoa Landois
Britt (Short for Britton :P)
Magic
Some guy who lived in the California desert and called programs "frogs" and called testers "froggers".
