make a php script with this in it:
PHP Code:
<?php
error_reporting(7);
$templatesused='advertise';
require('./global.php');
if ($bbuserinfo[userid]==0) {
show_nopermission();
}
$bbusername = $bbuserinfo[username];
eval("dooutput(\"".gettemplate('advertise')."\");");
?>
upload that to your forum directory
then make a template called "advertise" and put your html in it using the $header and $footer like the other templates of your site
this checks to see if the person is at least registered to view the page
