Q: What are linked contacts?

Basically it is a way of establishing a relationship between contact entries that are for the same purpose (or business as the case may be). It doesn't mergethem, but makes contact info from both enties available.

Take heed, however, as linking a contact removes the "linked contact" from your actual contact list and puts in under the contact you linked "to".

I wish I would have known this before I linked them.  Now I can't unlink them.
