BuddyPress.org

Adding a new menu item to the member theme, NOT the top bar. I did this with my recent example of “social” (view the screenshots):

This is a clean slate version of that above, if that makes sense.

EDIT: Duh. This actually DOES BOTH. This will add the same menu item in “my account” WITH submenu navigation in the grey “BuddyPress” bar that is present on the top page when you login.
