Just set up a Peer to peer network with Max 6.0 on all 3 computers. The first as the server and the two others as Workstations. How do I get the two workstations to see the data base on the server.

Next, how do I transfer existing data from a totally different computer into the server so that they can start off where they left off.

>How do I get the two workstations to see the data base on the server.

On the server: Share the folder.

On the workstations: Use File > New Address Book... to point them at the shared folder.

Maximizer backup and restore is probably the easiest.
