Creation here in America. They aren't near as much fun as fan-run conventions, but there is definitely less opportunity for fan "disputes" revolving around them!

Actually, Creation has been at the heart of disputes, the main thing being the rights of the performers to give their audience access to them. Several performers didn't pay enough attention to the contracts they signed with Creation and found out they were banned from doing the fan-run cons. At one Creationcon, two Trek stars were told they could not, as they wished go out and mingle with the fans once they were done with their assigned duties. After all, people might get signatures without having to pay 50 bucks for the privledge of standing in line for one, thus costing the con money.The actors, on the other hand, felt the fans were the customer of the series, and that they deserved more in return for their support than to be taken for every dollar they were willing to spend. The actors bought tickets to the con at the door and came back in order to be able to mingle. Of course, this isn't fan-vs-fan, but then, some fans were boycotting Creation and others weren't. I've never heard of an art show at a Creation Con (my husband and I do art, so we try to keep are ears open). Frees them from any accusations of censorship, I suppose, but provides less opportunity for fans and fan artists.
