The CRIWG workshops have been motivated by advances in computer-supported cooperative work (CSCW), and by the need for CSCW to meet the challenges of new application areas. This workshop aims at providing a forum for academic researchers and professionals to exchange their experiences and their ideas about problems and solutions related to the design, development and use of groupware applications. - searchers report their ideas, models, designs and experiences to CRIWG submitting full-paper contributions to present achieved or mature works, and shorter papers to report work in progress.
