A threaded text discussion or chat system includes a client graphical user
interface that is rendered on display screens of user computers. In one
implementation, the user interface includes a threaded discussion message
pane and a social accounting pane that are rendered simultaneously
adjacent each other on the display screen. Within the threaded discussion
message pane, messages or turns are rendered or listed in a threaded or
tree structure. The social accounting pane displays identifying
information about each past and current member of a discussion.
