Play2Train Open Content Alliance Basically they will offer free land and infrastructure + services to anyone who wants to teach emergency preparedness or related courses!
The Play2Train Open Content Alliance (POCA), which is evolving from the Play2Train activities, represents collaborative efforts to build a permanent self-sustaining archive of open source virtual worlds, including their content and applications, to support public domain emergency preparedness training and exercises.
The virtual content is implemented in the Second Life ™ platform. The powerful user content generation system of Second Life ™ has allowed us to build a sizeable set of virtual environments for emergency preparedness exercises in a fairly short time.
