Hi John,

Registered Users is an option in Permissions, and refers to all signed in users anywhere on Voice, who have not opted to join your site. You can't see a list of these users anywhere. So really for permissions purposes it would be unusual to treat these users any differently from The Public (i.e., not-logged-in users).

You'll see users awaiting approval on the Members Page too - there will be a "Needs Approval" filter in the left column. If there are no users awaiting approval then this will not show.

You also can't see a list of users who have been denied membership. We don't keep this information in the database.

There's more information about members in the documentation, here.

Thanks

Joe
