If you save the presentation as a "PowerPoint Show (*.PPS)" and the end user has
PowerPoint or the Viewer installed, it should open in Slide Show mode when they
open the attachment in their email client. I say "should" because if they are
using Outlook Express it might not open for them. If that happens, have them
save the file to their hard drive and then double click on it in Windows
Explorer.
