@Null: of course, you get all roles’ data. I meant you can get each role’s name from the returning result of $bb_roles->get_roles() (I thought you was going to do something special). However chrishajer has told you the useful information for all your need, you just need to read from https://trac.bbpress.org/browser/trunk/bb-includes/template-functions.php#L1296 to 1311. If you really want to do something with bbPress, you have to read the source of bbPress.
