Good suggestion. I'm still tinkering around with it.
A post will now list replies (if any).
I think I'm abandoning the 'sections' idea. I'm not sure it would be that useful, and I'm feeling lazy.
There is now an area-wide announcement when a post is made, although each board can have its own or have none at all.
Note that, due to an implementation detail, the poster doesn't hear it
