The purpose of this training is to familiarize you with menus in Drupal and enable you to practice in dev so you feel comfortable working with menus.
Go ahead and go through each of the videos to familiarize yourself with what he is covering. Then go sign into dev samhales.com and go back through the videos and actually do what he is doing. Do not worry about damaging dev. When you are done I will overwrite dev with live and reset it back to the way it should be. Play around with this until you are comfortable with menus. This is a critical skill for our IA (information architecture work).
