Good suggestions, and I think for the time being we’re all waiting for the 1.0 release before we start documenting code. Until then, any of it is subject to change at any point.

Once 1.0 is out there is a benchmark to start documenting from, in my opinion.

I can give you a hint though, check out the /css directories in each plugin, check out the member-theme, the buddypress-home theme, and you can also create a file called “site-wide.css” and put it in your /css directory for your home theme, and put all of your site-wide CSS changes in there.
