Hi Daniel: More and more publishers are providing PPT's as instructor resources. As I've indicated, these have useful information but they are not formatted to be real enjoyable to view (plain). I like to make my own slides, both for sequencing but also for allowing me to stop and discuss, or even do a brief demonstration, then come back to the slides. This not only makes things more interesting but keeps attention, students focused, and allows me to add the information I want to emphasize. Regards, Barry
