For some reason, after a couple of years of existence, my blog is now being targeted for random comments from a location (or locations) overseas. This morning, for instance, I had to go through several past entries, a time-consuming process, and remove the comments, which had absolutely nothing to do with the subject of the blog entry itself. Therefore, reluctantly, I am, for the time being anyway, changing my settings so as to disable comments by anonymous readers. I'm loathe to do this, as normally I learn something from the comments readers take the time to post. However, those who wish to contact me can do so by clicking on the "Contact Sam" link to the right, as well as through my university email address, also listed on this site. After a month or so I'll change the settings back to allowing anonymous comments, but for the time being I'm deactivating it.
