Manage memberships at the network’s main site (the primary domain of the network) and provide/restrict access on subsites in the network.
This add-on allows you to sell memberships at the main site that provide access to members-only content on a site or sites throughout the entire multisite network.
Let’s say you have a network site about all types of pet care. You have the main site (www.petcare.com), and a site on the network for various type of pets (birds.petcare.com, cats.petcare.com, and dogs.petcare.com). Using this add-on, you could offer a membership to one specific pet’s subsite (Bird Level OR Cat Level OR Dog Level). Then, you could also offer a Premium Level that includes access to all of your pet care subsites.
All of the membership levels and users are managed on the main network site. The subsites look to the main network site’s database to mirror the membership levels available and to check a user’s access.
