Hi,

Currently sites are completely independent with different users and roles. When you create a new site, a new admin user is created for that site, its not the same admin as the first site. Users would have to register on each site and login to each site.

I do see the use case for being able to create multiple sites with a common user base and at some point I will implement that as an option, but in the current implementation there is no relation between sites, they are completely separate.

Hope it helps,

Joe
