BuddyPress.org

This has been a real deal breaker for me, as I am the author of:

https://buddypress.org/forums/topic/make-member-theme-very-similar-if-not-the-same-as-buddypress-home

and

https://buddypress.org/forums/topic/how-can-we-integrate-the-buddy-press-theme-with-the-user-blogs/page/2

however, we may have our solution here:
