I learnt PowerPoint from my secretary long time ago, then I use it almost everyday, discuss with her sometimes, check the help function in PP. My secretary learnt it from internet, she said that there're a lot of tips and websites regarding PP. She just utilized her lunch hours to learn and she became an expert within a few months. Of course, she's smart and she uses PP very often.
