I'm interested in feedback on the new "groups" feature in Ning that I've added to Classroom 2.0. At first I wasn't sure of how helpful it would be, but I've got some examples of additional groups that I think it would make sense to start for more targeted discussions of Web 2.0 in the classroom:
Foreign Language Teachers
PE Teachers (yes!)
Now, I don't want to start them, because the person who starts them becomes the administrator of that group--and that shouldn't/doesn't need to be me!
