How do I completely hide a Book added to the frontpage from guests? I can change Guest user permissions on resources to completely hide, say, an uploaded file, but can't see the same permission for this in a Book. Any help would be appreciated.
If you add your book resource via the Main menu block you can then change the permissions in the main menu block so that guests cannot see it. You will have to ensure however that you have also set Site administration>Appearance>Navigation to NOT show front page activities in the navigation.
