interessantes Plugin, um Artikel abhängig vom Recht des User ein/auszublenden. Das kann man auf Artikelebene einstellen.
Das Plugin bezieht sich auch auf alte Artikel, also vor Aktivierung des Plugins: Once you“ve set the default level to „registered only“? (0) in the options screen, just log out and you will see that all of your old posts have gone. Log back in again, and there they are! The default view level is not added to new posts as a custom field. It is just applied to all posts that have no viewlevel custom field. So all of your old posts will count.
