Any PowerPoint Presentation gurus?

I'm working up a presentation and am wondering if there is any way to make a file that doesn't open in PP but just plays as a presentation.  I'm almost certain I've seen that before when Erin has sent me e-mails of like photos of troops or whatever.  I'm almost positive those were PP files... just one file attached to the e-mail and which opens up and starts running.  So far, I can only make a file that'll still open in PP.  I guess that's it for now.

Well, I figured it out.  No need for anyone to worry about me anymore.  

It seems you just go to "Save As" and save it as a "Powerpoint Show" file, a *.PPS.
