Reminders may be added to appointments in calendaring by setting the reminder drop-down box to a value other than None. When a reminder is activated, a sidebar item on the left will appear that reminds you of the event. By clicking on this sidebar item, you can dismiss the item or use snooze to bring up the reminder later.
You can also choose to activate an email reminder to send an email when the reminder activates. This can be your own email address, or can optionally be an alternate email address, like a cell phone SMS or pager email address.
