Use this list to ask and/or answer questions about homework, lectures, etc. The instructor and TAs are subscribed to this list, and will answer questions, but I almost always find that the questions and answers are of general interest, and that your fellow students often will answer more quickly (and more clearly) than the staff can. Students should be automatically subscribed within 24 hours of registration.
Questions not of general interest may be directed to the instructor and TAs, or just to the instructor.
