I've been Sweet n Leo, White Leo, Mister Leo, The Amazing Leo (and some others I can't remember). All around Leo, and all themed from Leo on Charmed (Leo Wyatt, hence White Leo).
I joined Gaia in '05 after a suggestion from a friend on a MMO. Got hooked and stuck around for a few years. Became a moderator (Site then Global) before stepping down in '10. Since then I've floated around other sites, but I never forget Gaia.
The one place I'm active is Tumblr, but that's about it. You can hit me up there if you want.
