Let me start by saying I haven't used this module - but I do have a suggestion based on other modules I've used.
I assume you're entering
www.townloafer.com
when you're entering the address. Have you tried entering
http://www.townloafer.com
instead? Some modules evaluate the contents of the field and if it doesn't start with "http://" assume it's a relative link inside your site and add the XOOPS_URL to the contents typed in the field....
Just a thought.
