The discussion of creating a new Sabermetrics FAQ gave me an idea.
How about creating a FAQ forum containing just the FAQ threads?
As others have pointed out, the FAQ threads need to be updated. And ideally, a FAQ should be a living document that's updated continuously with lots of input from the membership.. The discussion in this forum should also be confined to topics that are FAQ-worthy. The current FAQ has a good range of topics. To that end, set the privileges in the forum to allow no new threads to be started, but allow any post to be edited by its poster at any time... similar to a wiki.
