There is (in case you haven't noticed) an interesting discussion going on concerning TMWWT on the ACS blog. Right now they are in the same chapter as our puzzle concerning the notes is in. Please go check both of them out, if you haven't already, and take some time to read and comment. These topics are so interesting!
P.S. While you're there don't forget to check out Dr. Thursdays incredible and insightful thursday posts.
