It's a good point, and I considered just making a poll whenever I want someone new - I have places where you guys could vote anonymously so it wouldn't be horribly intimidating, afterall.
But I always felt there was no point because... how would I ever listen if someone says, hey, no, I don't think you can handle them :|
Although considering it now, I guess a review for, say, just the intro post, maybe? could work, and would help get crit on it before I play them. How does that sound o3o? And then if something's really off I can elaborate on shit (and ramble on personality info, for example).
