Yes folks. It's something new that I added. It is legit and is not a virus of any kind. If it bothers a lot of people, I'll get rid of it but basically what it does is watches for key words and if, for example, somebody posts an item that is available from a certain set of vendors such as Amazon, it will link that item to a place that you can purchase it. If somebody uses it and purchases an item, the site gets a small commission on it.
I don't think it will amount to much but it was free to try so I decided to give it a shot.
