DIGRA (Digital Games Research Association) has a newly developed site, using the Plone Content Management System that allows members (it's free to register) to contribute and help organize the site. They explain: "this newly designed website / publishing environment / research archive is continuously under development, and the final form it will take depends on the direction you, as a member of the games research community want to take it into".

This should be an excellent place to get ideas and share ideas on gaming applications in education:
