Works exactly as stated, and nothing more. This will make the component a real boon:
1. On unregistering, this component could (optionally) send a goodbye email.
2. The Admin should be able to edit the goodbye message to suit.
3. Users are also referenced in components such as Contacts, Letterman etc. It would be real nice if these references were removed un unregistering, too.
4. When passwords-save is enabled on browsers, the password field is filled with asterisks giving the false impression that the user does not need to enter a password.
