This page allows you to set links to another web site that will count hits. You can implement the partner system by creating a Partner site type block in the Blocks Admin.
The first section lists your partners, how many hits the partner link sent, the URL, image and description. It also give you the options to edit or delete your partners.
Add a New Partner: Just enter the URL to your image (blocks are 160 pixels wide), the URL to link to, and the description. Then click the Add Partner button, and create a partner site block in the Blocks Administration Page.
