1. Enable user modal example (part of http://drupal.org/project/user_modal )
2. Allow user to register without email verification
3. Allow anon users to access overlay
4. In example page click on login -- The overlay seems broken, as there is a JS problem.

The reason for the JS is in user_form_process_password_confirm() -- The JS settings that populate the Drupal.settings.password are called only once due to a static variable.
It seems that subform calls the same function twice, resulting with the element to be without the correct JS settings.
