I'm working on and off on the relationship guide, mostly jotting down ideas, because I'm still not sure how I'm going to organise it. And I'm having a hard time writing it without referring to LJ, too.

For the KB, what about a Wiki? Maybe only open to people who have demonstrated that they know what they're speaking about, though that would create a lot of work for admins (and probably outcries of elitism, as usual).
