This portal allows users to join any of the available Special Interest Groups (by default, all existing Technical Streams are termed Special Interest Groups - SIG). GDA will create additional SIGs as and when necessary. After joining a SIG, the user can either join the discussion on the available topics or start a new topic for discussion or simply read the available discussions on any topics posted by the other users without joining any SIG. This portal allows those who are not part of a Technical Committee to connect with any or all committees.
