The computer science discipline is well poised to provide leading examples of harnessing communications and computer technologies in order to encourage collaborative practices both within and between institutions. Students, academics, and institutions all potentially have access to their counterparts world-wide. This provides endless opportunities for sharing knowledge, accessing scarce expertise, making effective re-use of limited resources, collaborating to attract funding and influence policies, etc. Even so, within our own institutions we regularly miss opportunities to exploit appropriate technology for supporting both educational and administrative collaboration.The aims of this working group were to raise awareness of collaborative opportunities and practices, to investigate practically what collaboration means to academics, and to take practical steps towards promoting collaboration. The working group also aimed to identify technologies, i.e., techniques and tools, that offer pragmatic approaches to supporting collaborative schemes.
