Given the ongoing issue of posters turning up here which are basically fan art...I wonder if maybe some clarification of the posted submission guidelines is in order. I can see how the distinction between official posters and fan art, though obvious to anyone who is on here regularly, could be less than clear to newbies, students, casual users, etc.
It seems that much of the time when fan art is submitted, it's an innocent mistake. Someone could read the submission guidelines and come away with the impression that their "unofficial" poster, be it fan art, student work, etc, is eligible. I know it's loads of fun to berate hapless noobs in the vomment threads but maybe the requirement that only real, functional, official posters belong here, could be stated more explicitly, and save trouble all around.
