Heads up, I have added something that I think you will find useful.  I have added a MySQL reference to the Library!  This is more than a cheat sheet, I try to explain the things that are going on in there as we do it, so it should be a good way to not only see how to do specific things, but also understand them as well.  Check it out here and see what you think, if you see anything wrong with it or you have some tip of you own you’d like me to add, drop a line and let me know.  Enjoy!
