cheating on early homeworks and quizzes

We've detected at least four cheating cases on the early homework assignments and quizzes, and we'll be handling those cases starting Tuesday night. If you think you have cheated or otherwise violated our collaboration policy, now is your chance to save yourself: your punishment will be much less harsh if you volunteer an unsolicited confession before we contact you. If you might have any reason to be concerned, please send an email to charlie@cs.cmu.edu immediately.
