Can anyone play along? Yes anyone can play along even if you don't have a blog just leave your answer along with your e mail address so I can contact you to let you know you've guessed the right answer.
Are there prizes? As of right now no there are no prizes but things may change in the future.
What if more than one person guesses the right answer? The person who guesses the correct answer first is the "winner" that means who ever puts the correct answer in the comment section first according to the answer I have.
