That was very helpful, but I'm still failing to understand how to do what I'm trying to do. I need to add some content that is visible only to certain logged-in users who have a particular role. Ideally it would be a part of a page that would be visible or not depending, but it's OK if it's a separate page as long as the link to it is visible or not, depending. But I can not figure out a way to do either one. I can set the permissions on the new page, but there seems to be no way to selectively show navigation to it. This seems like it should be very easy, and I'm wondering if I'm not just completely missing something.
