The spam-bots have gotten too active on this blog, and too clever at “sounding” like actual people. Unfortunately, that means I’m going to have to turn on comment moderation. All are still very much welcome to comment, but only comments associated with a University of Minnesota user ID will appear immediately. All others will have to await approval by me.
You might want to consider installing the akismet plug-in. It takes a little work to set up but it is quite good at catching most of the spam.
