[xwiki-users] confirmed registrations

Hi all, I see in the "Access Rights" documentation that there are 3 ways it can be set up: Open Wiki Public Wiki Public Wiki with confirmed registration All of those options allow the user to register without forcing the admin to confirm the registration. I don't want users to be able to register themselves. I have a small set of special users and I want to be able to register them manually, or at least have to confirm their registration before an account is created for them. any normal visitor should not be able to modify anything on the website, and that includes registering themselves. is this possible? thanks Paul
