This one may be of interest to some…The International Society for Technology in Education (ISTE) has a Special Interest Group for Virtual Environments now. Their international conference has a Second Life playgroundc(maybe more worlds this year including Open Sim with places like ReactionGrid and Quest Atlantis, an ActiveWorlds K-12 place), lots of sessions about Second Life. The remainder of the conference is targeted at K-12 and teacher education. http://center.uoregon.edu/ISTE/2010/
