Class Axis

Mockup at http://www.slidemirror.com/show/d2z#3

Conversations: more like a forum than a chat.  Threaded responses.
  Trees rather than threads.
  How do we want to show this on a page?  After a few nests, the text gets really skinny and annoying to read.
  Each post has a permalink.

Calendar
  For events, assignments, tests
  Be able to compare schedules  (a la tungle.me)
  Google Calendar embed?  (.ics)

Chat
  Single and Group Chats?
  Persistent Chat Rooms? (like how campfire’s chat rooms work)

Classes
  Automatic assigned and grouped with people in your class
