I have the exact same problem. When a user tries to view a form that requires registration to complete (not guest post enabled) but they are not logged in the system generates a page with two items:

1. The message you specify in the front end form under “Unauthorized Message” which defaults to: This page is restricted. Please Log in / Register to view this page.

2. A login form with username, password, and submit.

The problem is that this form with the two parts has no place for the user to actually click a button to register. The login form generated by WPUFP DOES contain a link to register. But the login form that is generated on protected pages does not contain the same link.

Thanks for your help.
