Not sure how I form a "group" for e-mailing and also how do I delete a name from the address book that is no longer valid? Know these are basic questions but just not that familiar with computers in general and my new Mac in particular. 😕
To delete a card, highlight someone's name, and then tap the delete key on the keyboard or go to the Edit menu and select Delete Card. You can delete multiple cards/contacts by holding down on and clicking on each individual name to highlight them all then using the delete/Edit->Delete Card command.
