We allow fanart to be posted, provided it is correctly named (make sure it doesn't use the official image naming format, more details are on the Special:Upload page), licensed (listing who made it), and categorized (with Category:Fan Images).

as far as roleplays, the talk pages on this wiki are meant for discussion on how to improve the articles they are attached to. I suppose you could do roleplaying at the discussion pages, since those aren't really attached to the wiki articles and, as much as Wikia tries to mislabel them as "Discussion", they're basically designed by the software to be an open chat. Don't do anything illegal or harassing on there, though.
