A friend of mine who likes to visit this blog -- and occasionally comment on some of the postings -- was telling me that the comment feature at the end of each post didn't seem to be working.
I always enjoy reading what folks have to say so was annoyed to hear that it wasn't permitting anyone to post a comment. I haven't made any changes but Blogger did make some design changes a couple of months ago so maybe that's what disabled it?
No matter what caused it, I found a setting that seems to have fixed the problem so now you can comment to your heart's content!
One other related item: you'll also notice there's now a little "envelope" icon at the end of each post. That's for emailing a post to a friend, which is a new Blogger feature. Be sure to take advantage of that, too.
