I think I'm going to create a "Sandbox" page so people can edit pages,
practice with Wiki markup and so on. Though I suspect the "Preview" feature
serves most of that need...

That's what I was planning to do -- I've done a little bit of stuff on the
"exposure evaluation" page (relating to the use of a step tablet to measure UV
exposure) but I'd appreciate it if someone could have a read through, sanity
check it, and possibly complete the "How-to" section.

I have to admit that I'd rather like to see some stuff on UV etching --
especially relating to setting exposure levels. I'm not bothering with
laminating at the moment (though Mega have some UV-exposed solder mask that
looks like it might be fun to play with) but have got a few of the pre-coated
Eurocard-sized 1.6mm Microtrak boards (from Farnell, but made by Mega) and
some of the 0.8mm pre-coated CIF boards as well (again, from Farnell, but more
expensive than the Microtrak boards).
The step guides are sitting on my desk, I'm just trying to figure out how to
use them with positive-acting (where exposed areas wash away in the developer,
i.e. tracks are black on the artwork) photoresist!
