BuddyPress.org

btw, for who wants to help me, these are the functions I have identified so far:

add_filter(‘bp_get_member_name’, ‘bp_the_site_member_realname’);
add_filter(‘bp_get_displayed_user_fullname’, ‘bp_the_site_member_realname’);
add_filter(‘bp_get_loggedin_user_fullname’, ‘bp_the_site_member_realname’ );
