Membership information retrieval server, user terminal, message-sending terminal, and method for retrieving membership information and for sending message

摘要

A method for sending messages having the same contents to a group of users retrieved on the network is provided. The user sends retrieval requests from a user terminal (103a, 103b, 104a, or 104b) to a profile server (115). The profile server (105) retrieves other users in response to the retrieval request. Then, the profile server (105) sends the retrieval results to the user terminal (103a, 103b, 104a, or 104b). The user selects one or more users from the retrieval results to send messages to the selected users. The selected users are pooled in a list of destinations. The user sends an input message to each of the pooled users from the user terminal (103a, 103b, 104a, or 104b).
