I have just changed the blog settings so that I can moderate comments. I hope this will be just a temporary measure. Don't worry, no one said anything vile, but someone did leave a spam message that had me seriously concerned it was linked to a computer virus. If this is going to be the nature of spam comments, I want to make sure no one inadvertently invites anything harmful onto their computers. I check email frequently, so there shouldn't be too much of a delay in publishing your comments.
P.S. I did laugh out loud recently when I got an anonymous comment that said, "Get a life, losser [sic]."
