Seems that there has been a bit of a blog-up in the comments area.
I had moderation mode working to deter the spambots. However, for some reason my approval of those bona fide remarks did not result in them being posted as used to be the case. Why - who knows. I've already commented on the ability of p.c.s to be operating perfectly when shut down and then to re-open next morning with all sorts of problems and self-administering cock-ups.
So - moderation is off.
