I’m using a nice little plug in:
It seemed to do something funny to my menu/navigation though … I’m not looking into it: I’ll just use custom menus.
All the pages I’m adding under this page / menu-entry are private. They won’t be found without logging in (currently just Dave).
Doh. The plug-in seems to disable some of my appearance options (with the live preview). Oh well. Even with no page hierarchy for my few private pages, I can still use the custom menu for simulated hierarchy for front-end navigation. Will have to do.
