Regrettably, I have had to introduce a comments policy after a series of abusive comments were made. So now:
I very much welcome discussion on my blog postings. All comments are moderated, but approving a comment does not mean I agree with it, simply that I think it adds to the conversation.
I take no responsibility for the contents of individual comments.
Any comments that are abusive will be deleted without notice. Repeated infractions will result in a user being banned.
