Welcome to the RPC, Rei! We're glad to have you and I think I can speak for quite a few people when I say that we've all had a few bad experiences here and there with other RP'ers, so you're definitely not the only one there.
That aside, here's hoping our community can provide all the RP you're looking for and then some. People are quite helpful and open here, to say the least.
Also, that's a pretty smooth piece of art you have as an avatar.
