The contact author is the person responsible for correspondence with the program chair. We ask for additional information for the contact author, so that we can ensure timely communication and make the program accurate. We will only contact authors other than the contact author if we are unable to reach the contact author (e.g., because of a bad email address). Please notify us of any changes in names, affiliations, etc. in the contact author's information Note: If you have more than one email address, please put the second address under "Alternate Email". We will only use that address if there is a problem with the primary email.
