Teambox is a free service that allows you to create and manage a collaborative workspace for team projects. Within your workspace you can create a calendar of due dates, chat with team members, send emails, and most importantly post and edit files. If you create a group on Teambox, you are automatically the administrator of the group. As the group’s administrator you can send invitations for others to join the group, determine who does and doesn’t have editing rights, and monitor all group member activities in the Teambox.

Applications for Education
Teambox could be a useful tool for monitoring the progress of students that are working on group projects. Your students could also use Teambox on their own to coordinate the roles and tasks of each group member.
Teambox could also be a useful tool for teachers working on teaching teams to coordinate tasks that need to be completed.
