We can see the old quizzes at www.dropbox.com
The details can be found on the group web page at http://groups.google.com/group/cmu-quizzing
Upload old quizzes there so that the questions aren't repeated.
It could also be a good source to make questions for other quizzes you host ;)
And yes for members who graduate you can cure yourself from the FeRS "Friday Evening Restlessness Syndrome".
