At least one of the embodiments described herein relate generally to a method of communicating an engagement to a plurality of active mobile devices, wherein each active mobile device is associated with an active user. The method may include providing at least one communication socket to each of the active mobile devices; receiving location data from those devices, information related to an engagement. In response to determining the location of the engagement, a first notification is provided to nearby active mobile devices to determine the corresponding active user's availability. In response to confirming the engagement, a second notification is sent to the nearby active mobile devices to confirm the corresponding active user's availability. An active user is selected among the confirmed available active users and a third notification is provided with the selection result.
