I'm sorry for the inconvenience, but in an attempt to eliminate comment spam I've had to turn on comment moderation for this blog (in addition to the word verification that was already there). This means that whenever you enter a comment, I have to manually approve and publish it. When you click on the "Post a comment" link below, you will be informed about this new policy:
Comment moderation has been enabled. All comments must be approved by the blog author.
Please don't post duplicate comments - your comment will be published soon, as long as it is not spam.
