While on the customer list, if you change the "View Accounts of Type…" drop-down list in the top navigation to "Affiliates", the customer list will change to only show customers who are affiliates. On the right side of each customer line is a link to "View". Click on this to view affiliate details.

This page displays all the orders placed through the affiliate. You can't edit the orders from this page. The top half displays the order, the bottom half displays the information. The "Affiliate link to store:" is the HTML that you should give to the affiliate so they can put it in their link to your store. People who click this link from the affiliate site will be assigned to the Affiliate (any orders they place will be credited to the affiliate).
