I want to sync my address book with my wife's. We both use the same iMac but have different user accounts on the Mac and use our own email addresses, inboxes, folders, etc. I'd like it when I add an address book record or edit an entry that the same current info show up in her address book. Right now we have to remember for me to collect all changes, make them in my account / address book and periodically import that address book to her. You can imagine that potential for me to screw up that process! We just want to share the Address Book -- not our emails. People had suggested .mac but I can't figure out how to get it to share the same address book info synced across two users. It would be great if we could just share the same address book or have an address book that sat in a common part of the hard drive that would refresh every time. (We're running OS X 10.4.11 on a G5 iMac and use the Mail and Address Book programs). My challenge seems pretty straight forward but I'm having one of those "you can't get there from here" moments. I'm not married to the .mac / mobileme solution as I would have no use for the service beyond our address books and would rather not pay Steve Jobs ten bucks a month just for a common address book so if you have any suggestions I'm all ears.
