Reading through Sean's iTunes U Administrator's Guide, I have discoverd that when people sign up for iTunes U they have a choice of layout. There are two. The first is "Public Feature Page". This is the layout design that Steve and Mike B like. This is designed for public content. The second design is called "Course Page". This is set up for public and non public content. When we signed up for iTunes U, Course Page was selected.
We do not have the options to change the layout design to the Public Feature Page and visa versa.
