That sounds good. I've been thinking it would be great if we could get BlackSheep to write some documentation for the Edit Custom CSS feature in particular.
As the documentation team grows, it would probably be a good idea to start a thread that will serve as a clearing house for documentation projects, so we can keep track of who's working on what. You might even want to do that in a non-Staff category, so that other people will be able to see what needs to be done and volunteer to pitch in.
I'd be glad to help out with the docs as time allows. I'd be out of my depth trying to write about anything other than i18n, but maybe I can do some proofreading and copy editing.
