Pages and people
The kinds of page
Five types, what each is for, and the two that carry goals.
Who can see what
One rule, and the things that are deliberately not exceptions to it.
Adding and removing people
Bringing somebody onto a page, taking them off, and what they can see afterwards.
Admins
What an admin governs, and the one thing they emphatically do not.
Archiving and deleting a page
One is reversible and destroys nothing. The other is final and is only offered when there is nothing to lose.
