A few people have emailed to say they don't know how to add a comment, so I thought I'd try to help.
At the end of each post you'll see "# comments" which tells you how many other people have commented. If you click on those words, you'll receive another screen that says "post a comment".
After you've written your comment, you need to decide how to post. There are several choices, including my favorite - anonymous (I'm not a big fan of being forced to leave my name and/or email anywhere!) After you select your posting option, you can preview your comment, or you can publish right away. Remember to PUBLISH the comment or I'll never see it!
