Who's online - configuration

Ok, I think I got it - put this in a block with php enabled:

<?php
$number = db_result(db_query('SELECT COUNT(uid) AS number FROM {users} WHERE status=1'));



        if (user_access('access content')) {
          // Count users with activity in the past defined period.
          $time_period = variable_get('user_block_seconds_online', 900);

          // Perform database queries to gather online user lists.
          $guests = db_fetch_object(db_query('SELECT COUNT(sid) AS count FROM {sessions} WHERE timestamp >= %d AND uid = 0', time() - $time_period));
          $users = db_query('SELECT uid, name, access FROM {users} WHERE access >= %d AND uid != 0 ORDER BY access DESC', time() - $time_period);
          $total_users = db_num_rows($users);

          // Format the output with proper grammar.
echo "Out of $number registered users ";
          if ($total_users == 1 && $guests->count == 1) {
            $output = t('%members and %visitors online.', array('%members' => format_plural($total_users, 'there is currently 1 user', 'there are currently %count users'), '%visitors' => format_plural($guests->count, '1 guest', '%count guests')));
          }
          else {
            $output = t('there are currently %members and %visitors online.', array('%members' => format_plural($total_users, '1 user', '%count users'), '%visitors' => format_plural($guests->count, '1 guest', '%count guests')));
          }

          // Display a list of currently online users.
          $max_users = variable_get('user_block_max_list_count', 10);
          if ($total_users && $max_users) {
            $items = array();

            while ($max_users-- && $account = db_fetch_object($users)) {
              $items[] = $account;
            }

            $output .= theme('user_list', $items, t('Online users'));
          }

        }
        return $output;
   

?>

That adds the total number of users and then tells how many are currently online
