Title for reference. The Art board is up, so if you're logged in, go there and read the rules.
All creative content is allowed, so long as it's not against the law to post it. We'll see how well you guys do with some extra freedom.
EDIT: The art board is coming down, not for misuse of the extra freedom, but from lack of fucking activity. It's barren in there, man. Expect it to disappear sometime tonight.
