The present invention facilitates and tracks personal referrals made via electronic networks. In a preferred embodiment, using electronic mail delivered to a participant interface 110, a central controller 100 provides a Web page through which an individual may enter the electronic-mail addresses of those whom he or she wishes to refer. This spares the individual the inconvenience of generating his or her own electronic-mail referrals, and also enables the central controller to determine the format and tone of the referral. The address or contents of the Web page includes a unique identifier that is exclusively associated with that individual and a specific offer 120. In this way, the series of referrals may be tracked, duplicate referrals to the same electronic-mail address may be eliminated, offers may be withdrawn or modified, and referrals about an expired or withdrawn offer may be prevented.
