I would like to create subscriptions that allow our members to see only what that particular subscription allows them to view on the site. So if I create a subscription called, SSHAG Basic, and I only want the members that select this subscription to be able to view the pages that fall under the Main Menu, SSHAGGinga, how do I do that? Is this what the "Plan Relationship" does and if so, can you tell me how to do this or tell me the URL to the webpage that gives these instructions?
