Not Working For bbPress Roles

See:

Thanks for taking the time to respond. I had a feeling that bbPress was doing something bizarre when your code was getting passed the wrong info.

You can “map” your wp / members-plugin roles, to those used by bbPress. I have a custom role (created with Members plugin) called Student. I mapped this role to the “Participant” role in bbPress.

/**
 * FORUM - Role map
 * bbPress has its own internal ("dynamic") Roles, so we map our real wp roles to bbPress.
 */
add_filter('bbp_get_user_role_map','my_bbPress_role_map');
function my_bbPress_role_map($role_map){
	$role_map['student'] = bbp_get_participant_role();
	return $role_map;
}
