I'm looking for the simplest CMS that supports the ability to show different content depending on whether you are or are not logged in.
Simplest because the school users are not the most sophisticated or tech-savvy users.
The CMS is for a school site, which is not permitted to show some content (because of copyright etc.) to any users other than school pupils/teachers. So, not-logged-in gets the usual school bumf, how lovely we are etc, and logged-in gets super-sekrit course content (usually awful teacher-created crap).
