WordPress is behaving oddly in the comments department at the moment. I just failed to post a reply to Dr D’s last comment (#10) on Donnelly is miffed. Just in case, then, I am posting my reply here too. If that comment eventually appears I will delete it or this.
The problem seems to have been solved. There was a bit of a rush of spam, it seems, and my comment, because it had a number of links in it, was trapped in Akismet and took some time to appear… So go to the “Donnelly is miffed” post to rejoin the discussion….
