Here's just a handy-dandy link to a nice person's blog post sweetly explaining the reasons why one should use section breaks instead of page breaks when formatting in Word.
I am definitely likely to need this again, so I am putting it here.
And if any of you lovely people need something like this, you can click through and learn something (which will probably make your head hurt... so be warned. Formatting is not for the faint of heart!)
Hang in there!!
