Quizzard question/feature request

[moorezilla]

The Quizzard module is great! Thanks for making it!

I was wondering if it were possible to make an option where people could take the quiz without needing to give an email
address, and in such a way that the cookie set gets removed after they submit the quiz and get their feedback. I work
at a school where a lot of people share the same terminal, and often the browser is not shutdown between users, so the
quizzes pop up with the responses of earlier quiz takers.

Thanks,
Andy
