A couple of you have asked how to leave a comment if you don't have a blogger account. It's easy!
At the end of each blog, it says "2 comments" (or however many comments it has.) Click on that & it will take you to an empty box where you type your comment. Type your screen name at the end of your comment. When you've finished, look below the box where you wrote your comment & you'll see where it asks for your ID. You'll click on "anonymous". Then click "post comment".
Hope this helps! If you have any other questions, just let me know!
