greetings. ref article:https://www.afp548.com/Articles/Jaguar/emailsharing.html " To add an e-mail address you create a new property called "mail" with the user's e-mail address as the value. Phone numbers can be added by creating a new property "telephonenumber" with the user's phone number as the value." how did you know that phone numbers can be added by creating a new property " telephonenumber" is there a master list somewhere that tells me or tells netinfo property mail = email property Phone number = telephonenumber property Work phone = worktelephone....etc ????? basically I have a contact database and I want all of my users to be able to use the apple address book. Right now the only info in that address book is the users shortname. I know how to import users from character-delimited files how do i populate the address book / contact information? TIA --jeff
