Notice

Dear Readers,

I have learned that some of you are having a little difficulty with our comment section of the blog. We may have a broken link in our blog chain. Sometimes readers have to click on the word "post" twice after making a comment in order for the comment to go through. If you happen to get an error message when trying to leave us a question in the comment box, please try clicking "post" a second time. That usually takes care of the problem. Sorry for the technical difficulties.

Dr. Data
