Comment verification

The blog has been under attack from spammers in the past week.  If you get email notification of new comments, as I do, you must have noticed the barrage of dozens of daily spam comments.  Most of them haven't shown up on the blog, courtesy of Blogger's good spam filter.  Still, my email inbox is crammed full of garbage.  I'm tired of it and can't find the email I need to see, so I am temporarily turning comment word verification back on.  I know it's a pain.  When the spammers get discouraged and go away, I'll turn it back off again.
