BuddyPress.org

Just a note that in the latest version of this app, you need to use the modified WP plugin (sorry if this broke your existing setup):

https://github.com/yuttadhammo/buddypress-xmlrpc-receiver

This removes the need to access the plugin directory, calling instead:

http://mysite.com/index.php?bp_xmlrpc=true

which also removes the need to call wp-load.php just for the xml file.
