Thanks for your suggestions! The problem with allowing anyone with a .edu email address to register is that there are plenty of people who work for universities that have .edu addresses, but aren't teachers. There is a matching algorithm that matches students who are taking a certain course to teachers that teach courses similar to the one they are taking. The rating system is a very important feature, which I hope to get to work on soon!
