Hows this guys

Click the link in the center to create your own guestmap.
Take the code they give you, create a new template, call it MAP and paste the code in.
The take your index.php rename it to map.php or whatever, then
Search that file for
Code:
eval('print_output("' . fetch_template('FORUMHOME') . '");');
and replace it with
Code:
eval('print_output("' . fetch_template('MAP') . '");');
As you can see I used the vbAdvanced, but you dont need to.
Use the directions above and you are good to go.
