I would like to modify the default 'privacy level' of for a page class in Wagtail. In other words, when an admin panel user goes to create a new instance of MyPage, the default privacy would be accessible to logged-in users only, rather than completely public.
This seems like something that should have an obvious answer, but after quite a lot of googling, I can't seem to find any description of how this might be done.
Thanks!
