Ok so for this website I am thinking of something in which three things would need to be able to take place. You would need a part so students and teachers could talk or send messages and a place to act as a classroom. In the class room there would be a box in which people can comment on what is being said in the class (instant messenger), but the teacher would be able to lock the box so no one can use it tell he or she sees fit and delete comments at will. A blog where students would turn in work.
