What is the point?

The purpose of 2-Exchange.com is to provide webmasters with a free tool to handle, receive and submit links. 2-Exchange automatically check your link partners reciprocal URL for link back to your site, and if we don’t find it will send you a mail reminder. The same happens if you link partners URL falls to a PageRank of 0. We don’t link to your site or your reciprocal URL from 2-Exchange.com, our service is just a connection between you and your link partners.
