2 mininum?? So you can't just have one character???
I think that's a bit much to expect from everyone, especially since it's an advanced RP, maybe just give people open range to have as many characters as they want, but don't make 2 the minimum? I personally don't really want to play two characters, and if I did, I don't really play guys so I feel like I'd be playing two girls and throwing off the character-gender ratio.
