So we'd add another level of users... those who are "confirmed".. or "verified"... the terminology itself is flexible.
Thanks for your prompt reaction. 
As you mentioned at GitHub-issues, some counter system against spamming is must-have, and actually the most common SNS or BB employes the email verification to register.
I cloned the master edge and trying now, but Category Permissions is confusing I would suggest.
I observe that
checked = allow
unchecked = disallow
but, obviously, it does not work like this so far. In other words, the checking status does not reflect the permission status.
As a default nothing is checked, but in fact guest is restricted in some way.
When I start checking the Administrator, with logging out, the category disappear since guest has lost permission to view the contents even if their checking status is untouched.
I know this is under heavy development, but just let you know, the current checking status does not reflect the permission at all.
I wish I can help to code this section, but I'm new here, and wonder I can do right way.
Thanks.
