It would also be beneficial to make sure all the links work properly. Having the notes available before class would be helpful and answers to exams - after exam is returned. Keep up the good work with it and make sure that the links always work. I really do not find it necessary to make improvements to the current email and internet portions of the class. Information on the net is in an understandable concise format.
Email is also very user friendly and understandable.
Perhaps have the notes on the web before class. This would make it easier to add supplementary notes and not write down information available on the notes. I think that at the end or beginning of the online notes there should be a few questions or objectives for that day. It is an easier way to communicate when class isn't in session. Also, getting hold of your professor is easy because they check mail often enough where you can get a reply to a question quite quickly.
