You can add sessions to your personal calendar to receive reminders when they are about to begin. To do this, first add the session to your agenda by clicking the calendar icon on either the Session or Speakers page. If you are viewing recommended sessions on your My Agenda page, click Add to My Agenda.
Once you've added the session to your agenda, click the My Agenda icon in the top toolbar, then the calendar icon beside the session. This will download an .ics file that you can use to add the session to your personal calendar. Options include Outlook, Google, Yahoo, or Apple calendar.
