Edmodo is a private microblogging platform that teachers and students can use to send notes, links, files, alerts, assignments, and events to each other.
Teachers sign up for accounts, and then create groups. Each group has a unique code which is distributed by the teacher to the class. Students then sign up (no email address required) and join the group using the code.
All users can add any post or reply to their locker. After posts have been added to a user's locker, they can be organized and filtered using tags. Posts can also be sent directly to a user's own locker.
During the initial stages of edmodo, when a teacher signs up they are automatically added to the edmodo and support groups in order to give all early-adopters a chance to connect and report bugs.
