Creativity can be applied to every domain of knowledge and must be seen as an important competence. Supporting social creativity across different domains and disciplines in learning communities is an important part of collaborative process in both university education and in the context of large-scale international projects. In this paper, we present the experiences from the Virtual Summer School in Second Life as an attempt to support creative communities in a systematic manner. The Virtual Summer School acted as a forum for the presentation of innovative approaches, developments, and outcomes of research projects in the areas of technology-enhanced learning, serious games, and collaborative technologies, facilitating the exchange of ideas between students, researchers, and practitioners. To the end, we present lessons learned and implications for using this approach for supporting creative communities, outlining some recommendations and directions for future work.
