You can put one or more addresses in a vCard file, and attach it to an e-mail. This is an ideal way to share your addresses with others.
Just select one or more addresses from the Address List, and choose the menu command Actions/vCard/Forward by E-mail. You can also select the address(es), and then right mouse click on the main window, and choose vCard/Forward by E-mail from the popup menu. A new e-mail message will be created, and the vCard containing your selected address(es) will be attached.
