The ACM Conference on Computer Supported Cooperative Work <http://cscw2012.org> is a premier venue for presenting research in the design and use of technologies that affect groups, organizations, and communities. CSCW encompasses both the technical and social challenges encountered when supporting collaboration. The development and application of new technologies continues to enable new ways of working together and coordinating activities. Although work is an area of focus, CSCW embraces research and technologies supporting a wide range of recreational and social activities using a diverse range of devices. The conference brings together top researchers and practitioners from academia and industry who are interested in both technical and social aspects of collaboration. CSCW 2012 will be held February 11-15, 2012, in Seattle, Washington, USA. CSCW Workshops <http://cscw2012.org/participation/workshops.php> provide an opportunity to discuss and explore emerging areas of CSCW research with a group of like-minded researchers and practitioners from industry and academia. Workshops may focus on any aspect of CSCW theory or practice, established concerns or new ideas. However, radical new ideas expected to draw a sufficient number of participants are very much encouraged! The goal of a workshop is to share understandings and experiences, to foster research communities, to learn from each other and to envision future directions. For examples of workshop topics from the last two conferences, please review the CSCW 2010 <http://www.cscw2010.org/program/workshops.php> and CSCW 2011 <http://cscw2011.org/program/workshops.html> Workshop Programs.
