Multisite – Scuba Dive Log Site – Suggestions

Hello. I am building a scuba dive log site and would like to get some suggestions on the best way to set this site up.

The basic idea is that I’ll setup a WordPress multisite. The main site will be primarily informational. People will have the option to become paid members of the site to utilize some “tools”. One tool will be a scuba dive log.

The idea I have for the dive log is that when a user becomes a member, they will get a scuba dive log site created for them. The dive log site that is setup for them will only allow them to add and edit content on the front-end. This will be built using a custom post type and custom fields for the scuba dive log entries, etc.

I have a plan to setup similar tools in much the same way.

Is there a Membership plugin that would work with Multisite in this way? The memberships will have to work across the network of sites and be able to understand the specific sites a user would have access to.

Thank you in advance!
