Blog nuisances

Bother. Because of something to do with the internet restrictions at my work, I can't respond to comments on my own posts (though at least I can get in there more easily than previously) because the graphic for word verification doesn't appear, so I switch off word verification sometimes to do it, but, the second I do this, the spam comments start rolling in! Blogger seems to be removing some of them automatically for me, but it's irritating. And apologies to those who probably get emailed some of these comments.
