Collaborize Classroom is currently a free software for teachers to create a social network with your students. You have until October 31st to create your own community (social network) to collaborate with your students in a safe environment. You can see a video on the main page of a teacher sharing her experience using the software with her students. Sign up is simple, all the usual information. Once you decide to join there is a simple wizard that you can go through to setup your network with your students.
