We've also heard from a lot of people that have said they want to leave comments but aren't sure how. So, here's what you do:
Click on comments on the bottom of the entry. Type in the comment you want to leave, and then where it says 'choose an identity', check either the box that says nickname, and put in your name, or check anonymous, but if you do that make sure you sign your name in the comment box so we know who you are!
Hopefully that was explained well enough. :-)
