OK, I have created a new group called, "Newbies".

Posts and topics created by Newbies must use CAPTCHA, and their posts must be approved by a Moderator before they will be posted.

After five successful posts, Newbies become regular Users.

I'm going to create a new account to test this, and make sure I did it right. :-)
