Multisite access

Hello community,

I have a store front site that provides clients with the opportunity to have their personal information hosted on a site that resides on my network.

Each client will be allowed to accept users to their own personal sites. Each client site has a static front page that presents confidential information to registered members for their site while hiding confidential information to non-registered or site visitors.

My issue is keeping users (both my clients and the users they invite to their sites) separate across the network while allowing the average internet visitor to see the static front pages for every site on the network.

I’ve tried the “Network Privacy” Plugin which seems too restrictive. It does a good job of allowing only members of site A on the network to view only the contents of site A without giving them any rights to site B. However, it seems to block the casual visitor from accessing the static front page of every site on the network. This isn’t acceptable since my clients are going to need for visitors to access their front pages and acquire new members.

Does anyone know of a plugin or method for obtaining the security vs. accessibility I’m looking for?
