User A has Contacts, of which user B needs a subset (and for security
purposes, "share my contacts" is out of the question).  What's the most
efficient way to transfer that limited group of contacts from A to B?

What I've done as user A is to select the contacts to share, go to Actions >
Forward, send to user B, and have B double-click each attached contact icon
then "Save and Close."  Is there an easier method for user B to be able to
save all the forwarded contacts in one fell swoop?  Alternatively, is there a
faster overall method to accomplish the same task?

Many thanks.
