do i need to do another copyright panel again this year?
darkshardsyuki runs the AA, and if you're selling in AA, her say is what the rules are.
now, if you're asking about whether fanart is _legal_, that's a whole other ball of wax, and unless you want to go to law school, it's best to stick to what the AA heads tell you.
and, just a correction, no, fair use doesn't cover fanart at all. the possible protection for fanart actually comes from the 1st amendment.
that reminds me, i gotta go look up and see if "time and relative dimensions in space" is trademarked.
[EDIT] well, good to know it's not. for those interested in researching trademarks: http://www.uspto.gov/trademarks/index.jsp
