Abstract: A system and method is disclosed for electronically registering an event and reminding interested persons of the said event. The system comprises a client device with means for entering and sending event information, a client device with means for expressing interest in an event and receiving a reminder message, a server system with means for communicating with the client devices, storing event information, scheduling reminders, and dispatching reminder messages, and a telecommunications network through which event information and reminder messages are transferred between the client devices and server system. The server system contains a software module that uses rules, heuristics, and statistical data to calculate reminder time when not explicitly specified by the reminder recipient.
