If we were to do a wiki, it would definitely be a closed wiki...and we'd have to have a dedicated editorial team for sure. It would require some effort, and it would also separate the content from the current content management system, which is tied into search. If anything, I'd like to consider taking the best content and making CMS content out of, or even a vbulletin blog. We'll toss it around amongst the CL's and see what comes of it.
