I did this previously by hacking the forumdisplay.php where the SQL query was done to retrieve the child forums. I cannot really find where in the vB3 code this is.. Can someone PLEASE help me??

*beg*
Code:
// display sub forums
$permissions = $getperms;
//Forum info
//// BEGIN MODIFICATION Random Forum display for Sponsor Forum
if ($forumid == "40") {
$forums=$DB_site->query('SELECT * FROM forum WHERE active=1 ORDER BY RAND()');
} else {
$forums=$DB_site->query('SELECT * FROM forum WHERE displayorder<>0 AND active=1 ORDER BY parentid,displayorder,forumid');
}
//// END MODIFICATION Random Forum display for Sponsor Forum
