Ack. Sorry, folks, something went awry and I had to do an emergency restore of the site from an incomplete backup. This means that comments on the last three articles –of which there were a few dozen– are now gone.

I’m so sorry, there were some really good comments in there. I’ve backed everything up again (I really should create a new backup every time I update) so if you’re so inclined please feel free to repeat your comments or leave new ones. Things might possibly look unusual while I polish the edges back off over the next few hours but everything is working.
