A method of updating a network client with event data involves the network client registering with a computer server a unique association between a network user and a data object maintained by the computer server. The data object identifies a plurality of pre-determined events. The computer server is configured to receive event data and to update the data object in accordance with an occurrence of one of the associated pre-determined events in the received event data. The network client receives from the computer server a network client update indicating the occurrence of the one pre-determined event in the received event data. The network client then notifies the network user of the occurrence of the indicated one pre-determined event.
