Post History

This one is going to have to be [status-declined] as it is, but there's some other adjustments we can make that might solve the problems.

Making the main help page editable is more difficult than it might at first appear, and would be more prone to breaking; the current setup that simply lists posts automatically is more stable and much easier to maintain. Besides, help posts _should_ be discoverable and linked - I'm struggling to think of a use case for a page that's not visible in the list. If you're writing guidance, users should be able to see it for themselves without having to have someone link them to it.

Instead:

 1. We'll get categories fixed for help posts so that you can properly categorise posts.
 2. We'll add proper ordering so that you don't have to use a hack with titles.

We _may_ also be able to add an editable section at the top of the help center, but I won't guarantee that one until I've had a proper look at it.

There'll also be some network-wide shared help topics going out soon that all sites will have a copy of. Community moderators are welcome to write their own if they want to, of course, just by editing the network-wide post.
