For a non-commercial announcement.
There is a free add-on, discussed in this LifeHacker article, which, when installed, will give you a tab on your Office '97 programs called "menu".
Upon clicking on this tab of wonder, you will get ... can you believe it? ... the Office 2003 menus!
(I'm slowly learning the Office 2007 menus, but, when I'm in a rush, it's VERY nice to be able to just go to what's familiar, and grab what I need!)
