Ability to change registration status of users

As a SuperAdmin, I would like to have the ability to activate a user account. As it stands now, I can only activate the account upon setup. If an email invite has been sent, the account is stuck in a limbo state where the only thing a SuperAdmin can do is delete the account. I should be able to activate and deactivate the account while it is in the limbo state. Having to contact support to do this makes the SuperAdmin too restricted to be able to effectively manage the account.
