Unwanted comments

Sorry guys. I had to turn off 'anonymous' comments on my blog, because I suddenly got junk comments. There were four of them and they were all identical, and linked to some website or other. I have deleted them, but you can see their residual traces on the most recent blog entries. So, you can no longer post anonymous comments, or if you do, I get to screen them first. My blog is not an advertisement forum for strangers!
