WebRogue is an application for virtual presence over the Web. It provides the Web Browser with a chat subwindow that allows users connected to the same Web site to meet, share opinions and cooperate in a totally free, non moderated and uncensored environment. Each time the user loads a Web page in the Web Browser, WebRogue opens a discussion channel in a centralized server application, that is completely decoupled from the Web server, using the URL of the Web site as a key.
