A computer-implemented process of tracking events, is carried out by detecting that a first badge is within a personal-area network wireless communication range of a second badge, thus designating an encounter, and performing, by processor executing instructions read out from memory, an event logging transaction responsive to the encounter. The event logging transaction is performed by receiving, from the first badge, an electronic message characterizing an observation made by the user of the first badge relative to a user of the second badge, converting the electronic message received from the first badge into a pinpoint response, and generating an event record comprising an identification of an event type, and the pinpoint response.
