I love your tutorial. You manage to put a lot of knowledge into a sentence. I really need to learn to write this tight. And I love the use of the pointers. I really should have used those too. And you explained merge too :) I am linking back to your tutorial as it is a more complete one. It is so interesting that both of us minted and wrote these at same time :D

Good writing Amie. It inspires me to write better.
