Okay How would i make like member groups on a bulliten board see this snippet from a viewindex.php page

// Sort out who the moderators are and if we are currently a moderator (or an admin)
$mods_array = array();
if ($cur_forum['moderators'] != '')
	$mods_array = unserialize($cur_forum['moderators']);

how would u know if its a mod or a admin without creating it?(how would i create it)
