  •   ALWAYS save your projects using the following naming convention:


  •   DO NOT name your project any other way - Improperly named projects will not receive credit and you will be sad.


  •   NEVER leave your work on the desktop or depend on a flash drive - instead, save your work in a folder you can find later - preferably on a virtual drive where it can be backed up.
