From Matt Krokosz:
Class Chat is a way for students to chat with other students in their classes. Made by students, for students. It's super easy to use, all you have to do is sign up with your school email address and add your classes.Got a question about the HW?Don't understand something that's on the midterm tomorrow? Too shy to raise your hand in a giant lecture?Want to get a study group together but don't know anyone in your class?You no longer have to send an awkward email to your teacher, or even worse, send one of those embarrassing emails to the entire class...you can now just post a message on Class Chat!
