BuddyPress.org

@korhanekinci: it is available in the trunk, which contains the latest, bleeding-edge, development version of BuddyPress. Not for use in a “real environment”, but you can download it by typing svn co https://svn.buddypress.org/trunk in a your command line terminal (if you have Subversion installed). I believe it will be included in BuddyPress 1.1, expected release date August 17.
