RollCall Tidy is an Macintosh OS X application that 'tidies up' the contacts and groups in your OS X address book. Unlike Apple's Contact application, you can select a specific contact, review which groups he belong to, and easily click to add them or remove them from any group. Similarly you can review your groups, and edit them quickly and easily. You can export or print out list information is a variety of ways. RollCall Tidy simplifies your address book organization.
