Re: P2 Theme
Well P2 will work with BuddyPress, but finding a way to make the PS2 style sheet take effect has proven tricky. The page makeup for P2 is queer at best, with the sidebar called for just inside the top wrapper <div>.
But even after duplicating the page format in the BP template files as directed, the styles don’t seem to take effect. The only solution I’ve found is to hack the bp.css file extensively but even this is less than satisfying.
