I know some readers are still having problems posting comments. I just received the following email from a reader which might shed light on the situation:
Just wanted you to know that I was finally able to leave a comment on your blog. My wife works with a gal whose husband works on computers for a living. He couldn't leave a message on your blog, either, using Internet Explorer, so he tried with another browser called "Firefox" and that worked! We added the Firefox browser to our system and that did the trick. If you get anymore emails from folks having trouble leaving comments on your blog, you might ask them if they have Internet Explorer for their browser. For some reason, it doesn't work with your blog anymore, at least not for us!
Once more I'll state that I'm an absolute doofus when it comes to computer issues, but hopefully this reader's experience might be helpful to others.
