Address Book
A new feature in Address Book allows you to notify
a group of people after you modified your own info.
Set a template from Address Book Preferences to specify
what fields you want to use for newly created entries.
You don't want others to access all informations you added to your own card ?
Activate the " Enable Private 'Me' Card " option, then edit you card
and only fields you checked (or didn't unchecked) will then appear on your vCard once exported.
When adding a contact that was already in your Address Book, it asks you
to choose either to keep the old card, the new one, both or to update your existing card.
You can review the result of each option before choosing.
You can now add a field to specify a person's relatives
and easily access their cards then.
