Hm, it would be an option, but I think it's better to set up an entire new wiki. That way we have more control over everything.
I've been looking into several wiki engines and have found a few interesing ones that would fit the general needs. I'm also looking for free web spaces with the required options like PHP and MySQL and so on. I'll try to make a compilation of all the information I've gathered and e-mail it this week to those who are interested.
