Thanks HGZero, I am glad you liked the chapter but even more that you managed to find some things to change.

Now comes your real task. You need to decide what to do for assignment three, rewrite my chapter above, write it from a different point of view or write a new chapter that might serve as a background or even as a continuation. I really want you to get into the feel of the work and then make it your own.

I will look forward to seeing what you decide to do. I would also love you to let me know how you have found doing assigment 2 and 3. As the first student to try the new, improved level 2, your imput would be most welcome.
