Important: you must join the mailing list for your section. Mail will only be sent to your NYU email address, not to an extra-university address like an AOL address.
For section 004 (Marateck's 2:00 pm (A to J), Tue & Thur section) it is: http://www.cs.nyu.edu/mailman/listinfo/v22_0002_004a_sp07.
For section 004 (Marateck's 2:00 pm (K to Z), Tue & Thur section) it is: http://www.cs.nyu.edu/mailman/listinfo/v22_0002_004b_sp07.
There are two steps to joining the list; the first is to follow the instructions on the web page (writing your NYU email address, your name (THIS IS COMPULSORY), and picking a password), and the second is to REPLY TO the confirmation message sent to you by the system. Do this without changing the subject line; the message part can contain anything you want, or nothing at all. This list will be used for important announcements.
