BuddyPress.org

AFAK aka AFAIK usually means “as far as I know”. Forums are already in the 1.0 release, but none of the original posters other points. They area actually all being addressed by plugins with the exception of internal photo galleries which are coming after the 1.0 release. There is flickr plugin on buddypressdev.org though as well as Youtube. The invite system is there, but not finished yet.
