This semester we will be using an on-line website called Piazza to foster class discussion, questions, etc. The system is highly catered to getting you help fast and efficiently from classmates, the grader, and myself. Rather than emailing questions to me, I encourage you to post your questions on Piazza.
Our class page is located here: https://piazza.com/colorado/fall2012/csci44485448/home
I will be sending a link via e-mail for you to use to enroll in the class.
P.S. I see that some enterprising students already found the class page on Piazza and are already enrolled! :-)
