Don't worry, I like your posts and want you to be in. If you come up with a character you'd rather want to play, you can post a completely new SU in the OOC thread. I guess you can start from Viridian Forest or even the Digging Site, if you write about her journey up to that in the history part of the SU.
Do you still want the same starter? I don't know yet if any of the others are available. I'll also let you have one more pokémon on your team if you start in Viridian Forest, and two more if you start at the Digging Site. Since, I take it you don't want to write all the way from Pallet?
