Updating your email at the Student Information System (SIS)  - If you do not update your email address under the Student Information system you will not receive class "mass emailings" when your instructor uses the SIS system to email the entire class. Also if you want to add the class when it is full, and you email Prof J. and he agrees to add you, then you must email from the same email address as you have on the SIS system so Admissions can authenticate aqnd verify you are, in fact, the student requesting to be added through email registration.
