I haven't tested this but it "should" work...

open up register.php and find

PHP Code:

// ### DO THE UG/TITLE UPDATE ###
        $DB_site->query("UPDATE " . TABLE_PREFIX . "user SET usergroupid=$user[usergroupid] $dotitle WHERE userid=$u"); 


and replace it with (filling in the array with the groups you want to randomize)

PHP Code:

// ### DO THE UG/TITLE UPDATE ###
        $rnd_grps = array('7', '9');
        $user['usergroupid'] = $rnd_grps[rand(0,count($rnd_grps) + 1) - 1];
        $DB_site->query("UPDATE " . TABLE_PREFIX . "user SET usergroupid=$user[usergroupid] $dotitle WHERE userid=$u"); 


This assumes your users have to activate their accounts before they can use them, if that's not the case I can modify it.

Hope it works for ya
