@indietravel Yes, and no.....
I'm now using WP3.5.1, WPSEO 1.4.4, BP 1.6.4, BP Docs 1.3.1
Yes, WPSEO does set the titles/descriptions for the BP Docs custom post type pages - just like it does for the WP pages.
No, WPSEO still does not set the titles/descriptions for the BuddyPress (i.e. groups etc.) pages - i.e. WPSEO is not integrated with BuddyPress, which is a real shame in my view.
