Hi kb90 to stop people from accessing the admincp if they are not the admin or not logged in you'll want to read page 701 in the book for the answer.
Basically all you have to do is add the following to the very top of admin.php page:
Code:
<?php
session_start();
include "http.php";
if($_SESSION['access_lvl'] < 3)
{
redirect('index.php');
}
?>
