Listen, Karl may do what he says in regards to placing your link in a rotator.
But that does not mean you will get sign ups. In fact, it may be more difficult to get sign ups that way
because your in a rotator with others that are also trying to get sign ups. It's kind of a catch 22. It really
doesn't take a rocket scientist to figure it out. Less in rotator, means less money he has been paid, which
means less advertising. More in rotator, means more money he has been paid, which means more adverts
he can do but less likely you will get hits.
This has all be discussed before here already.
If you want to spend money, go over to adhitz or some other legit places and pay for advertising yourself.
