that is true. i modified the main register.php page (not the template – as i have a special flow for registration outside the standard bbpress way) and checked against the profile_info_keys and registered the error. But I guess one could override bb_new_user and throw a new error for a duplicate too

But, i’m not sure how one would go about handling the updating of a profile, on the main profile-edit.php page, i see this hook but its after the error codes have been checked. So I guess one could hack this page for the time being for a duplicate email and handle appropriately

if ( !$errors->get_error_codes() ) {

do_action('before_profile_edited', $user->ID);
