The document summarizes the Emerge project, a 28-month investigation of how to support online communities of practice. The project involves 28 institutions, 45 teams, and 210 participants exploring how to form an effective and sustainable community using Web 2.0 technologies. It will apply appreciative inquiry methods, which focus on identifying what works well in a community rather than criticizing problems. The project aims to learn about processes that support emergent technology-enabled communities.
