I've just updated on of my sites to 3.3.0 on my development computer and can't figure out how to set the registration properties so that more fields are required. On one of the sites I host the City, Country, and Region are required on registration.

This is not so difficult if you know how Logon to your site using either admin or host credentials. From the menu choose Admin -> User Accounts and click User Settings. On the bottom of that page you will find a setting called "Require a valid Profile for Registration:". Be sure to check that. In the registration page you will now see all fields that can be filled in. The fields that you have choosen in Manage Profile properties to be 'required' will have the red the sign on the right telling the user that is must be filled in.Hope this helped.

Hehe, that happens to me to I guess I am going to me make some screenshots and write something about this in my blog.
