Uh… PowerPoint. Right! I'll just fire it up here.     I just love PowerPoint! I've used earlier versions of the program in my teachers' workshops--but that was quite a while ago. I've probably forgotten everything by now.   You know what, Mrs. Lopez? If you've used PowerPoint before, I'm sure you'll be familiar with the new version. Why don't you try it out for yourself? Please, I insist.   Me? Oh, I couldn't. You're the expert! I don't think I could--
