Also, you may want to think about how you might credit people. I mostly mean that a few members of fandom have put a lot of time and effort into creating their own sort of information databases, and those would be a goldmine to any wiki that was created. Unfortunately, people may get upset if information that they've painstakingly gathered shows up on the wiki with no mention of their name. It seems like it might be a delicate problem, because recognizing everyone that has added information to the wiki would be ridiculous, but some people should get that recognition for work above and beyond.

Just a thought.
