Since there are already Wikis out there for already established characters, I'd say start one with your own. What you can do, if it's allowed, is to post excerpts on the forums you are on to get feedback.
I've never done a Wiki myself but I've used them a lot. Here's a question, how would you prevent others from editing it? From what I saw, on some Wikis people can add & subtract as needed.
Nope. Totally free! Although, I might add a Donations Accepted button to the site at some point. I refuse to put advertising on here. But I need a little bit of extra to help mitigate the cost of running the site. I'm still not 100% decided though.
The only advertising on my forum is from Proboards. I can see how people like the revenue from it.
Maybe you could sell services? I've seen that on promotion forums. People who may need a virtual hand at running a forum, the tech side, even graphics & designs. That would help give some more income. Some people don't mind paying people for help.
