I'm sorry to have to say that the number of spam comment postings has required that we turn off anonymous comment posting. There's been a massive boom in what seems like computer-automated spam comments with links to web pages that advertise cheap, nasty, bad-for-you products, mostly cigarettes.
From now on, you'll have to be a registered user to comment on this blog.
If you had something you wanted to say, but really didn't want your name attached to it for some good reason, you should email Mick at mwomersley@unity.edu
