December FAQ Scrub

[denise]

We've just passed 6 months of open beta, and we've been developing like madmen and madwomen, so there are a bunch of cases where our FAQs are out of date or there are new features that aren't documented anywhere but in code tours/news posts.

This/next week, I am making it my project to:

a). go through every single FAQ on the site to identify things that need to be updated (wrong limits, feature enhancements, etc)
b). write new FAQs for all completely-new features that aren't yet documented.

This is not so much to ask for help -- it's the kind of full-on scrub that I think is best done by a single person to make sure things don't fall through the cracks -- but it is a request for pointers! What things have you noticed that aren't documented/are underdocumented? (For instance, sticky entries aren't really well-documented at all, etc.) I'll be making my own list, and going through past code tours, but I never remember everything our site can do and could use a hand :)
