Abstract: A ConnectIcon View is employed to establish collaborative communications between a plurality of participants in a group. Specifically, it is a dynamic visual representation of the participants of a group being invited to communicate together with their presence information, lists of documents and URLs (Uniform Resource Locators) to be examined, and a set of mechanisms (email, chat, voice, and the like) to initiate communication, each of which can be billed to the originator or otherwise as desired. The available presence information allows a user to employ the best mode of communicating for the instant purpose, namely, either asynchronous communication or synchronous communication.
