The document discusses a scheme for peer-to-peer (P2P) based multimedia sharing in online forums and user-generated content communities. It proposes a system called Multimedia Board (MBoard) to support sharing of multimedia like images and videos between users in a P2P fashion to reduce load on central servers. Analysis of data from Disney discussion boards showed properties of forum usage that informed the MBoard design. Simulation results using real traces demonstrated MBoard can significantly lower the load on servers while maintaining high quality of service for users.
