I have had a few people say that they can't post comments because it requires you to sign in- It actually doesn't, you just need to click on "other". You can put your name in the spot that comes up that says "name" (interesting....) and write your comment in the comment box.
I guess there has been some confusion as to how to post a comment. Maybe now people can leave more comments so I know that this page is actually being viewed...hint, hint! :)
