Organization and Comunication are key for when setting up your course.  You need to make sure your students can progress through the course in its intended manner.  Commuicate with your student in what you expect in them and let them know how to get ahold of you if they have questions.

As technology is always changing or new technology is created, networking is a great way to expand one's knowledge of what tools are available.  You must evaluate to make sure the tool also fits your needs.  I liked the aspect that you should always evaluate the tools being used and checking out new tools.  Checking out new may allow you to find ones easier to use for both the student and the teacher.
