[Nate in Wisconsin]

I have a number of multi-page documents I want to put in a 3-ring binder.
I'm using Mirror Margins to give me space to punch the holes. I also want to
alternate the page numbers in the header so that they're always on the
outside of the page: odd pages on the far right of the header, even pages on
the far left of the header. I could do this in Word 98, but I can't for the
life of me figure out how to do it in Word 2007. HELP!
