Allow for hidden users

Hello,

I'm trying to hide the user admin (uid 1) in the stats and I found this in advanced_forum.module

function advanced_forum_statistics_online_users() {
  $list = array();
  $interval = time() - variable_get('user_block_seconds_online', 900);
   $sql = 'SELECT DISTINCT u.uid, u.name, MAX(s.timestamp) as maxtime
            FROM {users} u
              INNER JOIN {sessions} s ON u.uid = s.uid
            WHERE s.timestamp >= %d AND s.uid > 0
            GROUP BY u.uid, u.name
           ORDER BY maxtime DESC';
  $authenticated_users = db_query($sql, $interval);
  while ($account = db_fetch_object($authenticated_users)) {
    $list[] = theme('username', $account);
  }
  return $list;
}

I change this line:

WHERE s.timestamp >= %d AND s.uid > 0

to

WHERE s.timestamp >= %d AND s.uid > 1

Is not hard to do, but is the only way? would be useful a GUI to hide users and roles.
