Selected Application

The proposed application is a persistent, real-time, classroom specific chat service. Users login with university credentials and are shown a list of chat rooms for the classes in which they are currently enrolled. Upon entering a class chat room they are presented with a global chat where the teacher and students can exchange questions, answers, class lectures, draft assignments, and links to relevant material. Note: There is a lot of room for add-ons. The simple base of this application is based on the chatroom interface.
