Abstract: A method of operating a matchmaking service, to include the feature of monitoring geographic proximity of paired participants deemed to be matched by computerized compatibility analysis, and communicating signals to each when a predetermined threshold of geographic proximity is achieved. Proximity is monitored using for example GPS enabled communications devices, such as cellular phones, which may be used to receive the signals. The signals may include previously logged characteristics of each member of the pair. The participants may then respond affirmatively to the signals or alternatively may decline the opportunity to meet.
