PHP Code:

if ($bbuserinfo[usergroupid]==XX) {
eval("standardredirect(\"".gettemplate("templatename")."\",\"filename.php?s=$session[dbsessionhash]&action=loop\");");
}

if ($action=="loop" && $bbuserinfo[usergroupid]==XX) {
eval("standardredirect(\"".gettemplate("templatename")."\",\"filename.php?s=$session[dbsessionhash]&action=loop\");");
} 


This would redirect over and over to itself, just place it anywhere you want it to look and change the templatename and filename to the correct names, then make the xx to whatever use group it is that you want this to happen to.
