This invention is an online system to forward and discuss messages of common interest among members of the system. The system is based on a central server that manages all member accounts, messages and message flow among the members. The system introduces the concept of private comments on a public message. While the message is open to all members of the system, each comment on the message is restricted to be viewed only by members to whom the comment is sent to. This allows an email like interface to forward and discuss the same message among different groups of people. The system also provides metrics related to the overall reach and popularity of the message.
