dear sir/madam:
i would like to type a letter on a background, say flowers,
and save to documents. then later send an e-mail with this
attachment. i have tried several times e-mailing myself, i get back the letter 
but no background.when i click on save
as, i title the doc. then there are 21 choices for type. could
you please tell me what type to save in? thank you for your
support.  happy holidays,  regards, gary.
