This module was created to increase your link popularity (A hyper link pointing to your site from another site). Inbound links effect your link popularity and your rankings in many search engines such as Google, MSN, Yahoo, HotBot, etc. Many search engines use Link Popularity as a factor for determining page rank.
The way this works is as follows. If 100 websites use this module and all 100 sites are listed in the list, then each site is linked to 100 times.. and so on.
Sooo... the more sites that use this module the more popular that site will be. The best part about it is, you do not have to do anything but upload and activate the module. All emails from the form are sent to me, the links file is stored on my server and the links are updated by me. So as sites are added to the list, the list changes dynamically on your site.
