I've downloaded and installed this plugin (half your tutorial gone but not needed) but I can't get it to work.
The login widget puts a login widget in the sidebar but with no title, I've checked the html with firebug and there is no title within the widget title tags.
The login page is blank no matter what I put in the login page options and the same thing happens with the registration page. (again, I've checked the html).
Shame as it is exactly what I was looking for.
