A team communicator is the person in a team that keeps communication going by connecting to team members, even those that are not directly involved with the communicator's day-to-day work. As such the team communicator plays an important role in the social network of the team because he is able to dispatch news and requests to the appropriate team members.

Team communicators are often power users of communication tools like chat rooms or mailing lists that allow them to communicate with a large number of people at the same time, synchronously and asynchronously.
