ABSTRACT:
A method of communicating digitized speech from a transmitting forum participant comprises the step of receiving a data structure that includes said digitized speech. The data structure is analyzed to determine whether the digitized speech is redundantly represented in a plurality of forms in the data structure. A portion of the data structure is forwarded to a receiving forum participant, thereby communicating the digitized speech from the transmitting forum participant. In this method, when the digitized speech is redundantly represented in the data structure in a plurality of forms, the forwarding step includes a step of selecting one or more forms, based on a function, from the plurality of forms in the data structure. A representative function includes a determination whether the receiving participant is a paid subscriber.
