BuddyPress.org

Aran-

You are correct. Andy has themed the BuddyPress forum theme to look just like the rest of BP.org.

At this time, he does not plan on releasing this theme. He wants to keep the bp.org brand distinctive. Imagine if many of the new BP installs used this theme. It might confuse people when coming to BP.org. BP.org needs to maintain a unique identity. It is, after all, the place where everyone else comes for guidance.

Of course, everyone is free to style their own theme.
