... group a bunch of pages together so it's easy to navigate between them?
Should I put them all in a book, or use categories, or a header or sideblock or somesuch?
(Here's an example of such a collection).
I mean, my ideal situation - which may not be possible - is to have a menu on the left or right to navigate to any of those pages. Those aren't the whole wiki, of course, they're just a corner of it.
