How about a TalkBass Wiki area?
For those that haven't come across them before,
http://en.wikipedia.org/wiki/Wiki has a good description, and is actually a Wiki itself.
They're basically web pages that can be added to/edited by anyone. They're best used for keeping information, and not chat/discussion (that's what the forums are for!).
Since anyone can edit them, they're usually kept clean, typo free, up to date and readable by a community. They log all changes made by users, so it's easy enough to view a certain revision, delete all changes by user X, etc.
Could be useful on talkbass to replace many of the sticky threads, for FAQs, for gear reviews and the like.
