I have only ever been on a handful of places but, here they are!
Project Infinity: Sorcha, Buffy, some staff alt whose name I don't remember. I did apps during the second or third staff group? Though that was hilarious since I actually was not a comic fan? Mostly I just made sure things made sense. I honestly had no idea that staff were supposed to run things on games cause they never, ever did here.
Tenebrae: Isabelle, Sam, Aerin, and Cataclysm (staff alt). My first stupid dice game!
BuffyandAngel (Aha! I figured it out!): Morgan, Anya
Devilshire: Marley, Claire, Anna, Abigail, Mandi, Drynwyn (staff alt)
String Theory: Sabrina. Didn't play there very long.
Star Wars Sagas: Trilony. Didn't play there long because the game imploded after the movie arc. This is also where I learned to hate roster characters.
Stranger Than Fiction: Clara
Arx: Sabella (everyone's favorite), Adora (no one's favorite), Miella (for a hot second), Gretchen (the one and only!), Korka (The one everyone either hates or loves there is no inbetween!)
Gray Harbor: Clarissa
I was on The Reach for like a hot second. I don't even remember my character name. I was in one big plot related scene where I questioned the wrong person? Honestly, I had no idea what was going on or who was who. And then I had people paging me telling me not to do that or I'd be shunned and people paging me thanking me for standing up to them and I was like, ugh, this seems like lots o' drama and never logged in again.
I would've played more places, but @HelloRaptor never showed me how to make a Mage that could turn people into lawn chairs like he promised! Also jesus christ, you people and your WoD rule discussions. So complicated!
