You tell your rotator what sites to show by adding the pages you want seen. You add the pages by clicking the 'Add Site' button and entering the page link/url. Once the page has been submitted you must then confirm it from your 'My Sites' page.

You can check to see if your rotator is working by visiting your rotator link:
http://www.myultimaterotator.com/rotate.php?rid={YOUR ID}

The rotator operates continuously as long as you have it entered into the rotation of a traffic exchange and have credits assigned to the link. It will continue running until the credits have been depleted.
