Our group has been developing applications for the Opensim virtual world platform for a number of years. We describe our goals, the design approaches that emerged, and our development processes. We share the best of our lessons learned. These stories from the trenches will be useful to individuals who (1) are interested in the behind the scenes aspects of our effort, (2) are looking into starting their own adventure in developing serious virtual world applications or (3) are interested in how we are facilitating virtual learning environments.
