I have set up a wiki site on Wetpaint.com titled "Creating the Virtual Playground". Its url is http://createplayground.wetpaint.com
Access is restricted, so I would have to have your email address to invite you. If you and others sign up, we can decide together how we want to run it. I'm pretty much a consensus type of collaborator.
I chose restricted access because I want to retain the focus described in the site description:"Creating the Virtual Playground is a wiki site for members of Playground 2.0 which is connected to Classroom 2.0.
The "founding" idea is to create virtual playgrounds for children of all ages where learning is the focus.
