These should be basic.

1. No fighting. If some one disagrees with you, leave. If you continue it in the P.M. that is up to you, but not in threads.
2. Keep the threads to one thing. Why you don't particularly like something, but you don't hate it. Don't start threads stating you think this character is amazing, or why you hate them. You can deviate in the comments, but don't start wanting a fight.
3. Be kind. Be polite. Be courteous.

If the group gets bigger, then I will be looking for staff. I will let you all know when.
