Well sorry, but I can not find the javascript snippet someone once submitted, and I don't write javascript myself, but for someone that does, this would be a pretty quick couple lines of code to write. If you'd care to make a small donation via the Paypal button to the right, I can probably hire a javascript programmer to write what you need, and add the feature to the current version, in essence you would sponsor the feature.

The other option is to edit the draw_sites function in the includes/function.php file to make it show a plain URL, but since outbound clicks would not be counted, you would also need to remove the "Whats Popular" links from the menus.
