The Ninth Circuit has issued this notice
The United States Court of Appeals for the Ninth Circuit will begin implementation of the appellate version of a new case management system, CM/ECF case management/electronic case files on March 3, 2008. In CM/ECF, participants in a case can provide the clerk with an e-mail address and agree to receive an electronic \”Notice of Docket Activity\” NDA when the court takes an action in a case. If counsel or parties have not provided the clerk with such an agreement and correct e-mail address, their copies of the court’s orders, calendars, opinions or other notices will be mailed to their physical address through the U.S. Postal Service. Users may specify multiple e-mail addresses for their notices.
