There are rules in the fanworks, but you'll understand them quickly.

1) Don't flame a person's work. They worked very hard on it, so don't even try.
2) No smuts. If it's smut, link it and post a warning saying that it's not available for little children ^_^
3) Be creative. That's not even a rule.. ^^;

Alright, let's get those artistic fingers working.
