Contact Change allows you to find those with whom you have lost contact. Because Contact Change is driven by those who have registered, each user selects the minimum contact information that is required to find himself or herself. This means that while one user may only require you to know his or her first initials and an email address to be found, another user may require you to know his or her full name, the city he or she last lived in and the city he or she attended high school. By default, in order to find someone you will need the person's initials, phone number, email address, and gender. Your best bet to find an individual is to enter as much information as you know.
