INFORMATION EXCHANGE METHODS AND DEVICES

A multi-client (e.g., multi-person, multi-user, multi-device, or multi-node) information exchange method includes receiving a first request for a first client to enter a multi-client information exchange interface. The information exchange interface is operable for displaying information sent from clients including the first client. The information exchange interface is provided to the first client according to the first request. An exit request for the first client to exit the information exchange interface is received. The information sent from the clients is deleted in response to the exit request. Subsequent to the exit request, a second request for the first client to enter the information exchange interface is received. In response to the second request, information sent from clients since the exit request was received is displayed.
