A community server categorizes and accumulates messages exchanged by users on a virtual community for respective topics. Since the community server includes a thread moving unit, i.e., a mechanism that allows an administrator to move a thread as a set of messages posted to a given virtual community to another virtual community, each user can utilize collected and accumulated knowledge via his or her desired interface. Since the administrator can move a thread between communities, virtual communities can be combined or divided. |
