Technically, putting a wiki on the Formula 16 website is not too hard, but running the things is surprisingly difficult. I've had a lot of trouble with spammers on wikis that I've run in the past - they come and delete your content and insert links to their websites (the idea being to gain Google page rank). It's not hard to revert out their changes, but it gets boring very quickly.
It's probably not a huge issue at the moment: our website has a miserably low page rank, so is not very attractive to the spammers (I'll start a thread about that, as it's something we should address...)
The wiki software that wikipedia uses is mediawiki. I've not used mediawiki, but I've used several others and they all suck in their own little ways...
