Eve, I'm sure your large readership and the number of comments you're receiving already confirm the title of this comment but I've been trying to email you to congratulate you personally. Has your email address changed? Anyway, I just published a review of your Trivia Game and your website on my blog: http://mathnotations.blogspot.com/2008/03/best-pi-quiz-on-web.html You deserve the title, Best Pi Quiz on the Web! Thanks for the wonderful resource.
It must be gratifying to you to see how many educators and others are looking for interesting Pi Facts/Activities this week! Then they land on your site and are captured...
