it can't show another color than blue, becaue your variable $userinfo isn't defined in forumdisplay, so the script allways runs the else condition.

you have to add a query to get $userinfo, or it would be impossible:

PHP Code:

    if ($thread['postuserid']) {
$userinfo=$DB_site->query_first("SELECT username,usergroupid FROM user WHERE userid=".$thread['postuserid']);      
if($userinfo['usergroupid']==6) $color="red";
elseif ($userinfo['usergroupid']==5) $color="green";
else $color="blue";

$thread['postedby'] = "<font color=".$color."><a href=\"member.php?s=$session[sessionhash]&action=getinfo&userid=$thread[postuserid]\">$userinfo[username]</a></font>";
    

} else {
      $thread['postedby'] = $thread[postusername];
    } 


i know the code is optimizable, because it added a lot of queries, but it should work..
