[TECK]

ok i did this...

$threads=$DB_site->query("
  SELECT * FROM thread " . iif($thread[pollid], 'LEFT JOIN user ON (user.userid = thread.postuserid)', '') . "
   WHERE open=1 AND open<>10 $iforumperms ORDER BY lastpost DESC LIMIT 5
");

if ($thread[pollid] and in_array($thread[usergroupid], array(5, 6))) {

i know that's not good because i need to grab the threadstarter id. postuserid will not give me much. is enough that someone posts to the thread and my poll is invisible...
i think i'm gonna have to end with adding a usergroupid field to table thread.

let me know id there are ways arround. thanks.
