So, I’m only about three months late here; what can I say… I had the best of intentions!

Links to resources related to Microsoft Word, and entire Office suite:
– Microsoft’s “Mactopia” page; Mac-specific resources for their Office software. Check out the “Help and How-To” link at the top of the page, then the Featured Course, and Featured How-To… One downside to this resource is that it’s almost exlusively geared towards the latest version of Office for the Mac, Office 2008. It doesn’t mean you won’t find helpful tips that apply to earlier versions, but you just might have to dig a bit, or be willing to experiment in earlier versions…
– The templates page for Office 2004 (an example of what you can find if you dig a bit at the site linked above). A whole bunch of handy templates for specific purposes that you can use in Office 2004. And who knows, but most of ’em would probably work in the older version (“Office Vx”) as well…

-“Create letterhead templates in Word”, from A handy tutorial for figuring out how to make creative graphic letterheads in Word. It will teach you a lot about using the Header tool as well. [Subscribe to the CreativeTech weekly Tips newsletter as well, it’s a fun graphic-design related resource.]
-“Word:mac”; a “Microsoft Most Valuable Professional” site containing tons of helpful resources. I’m surprised it’s not been updated with info on Office 2008 as of yet, but since most of us probably don’t have it yet either, maybe that’s a good thing!

These are just a few things offered as jumping off points. I hope they help. Let me know if you end up needing more direction, or have specific questions.

Have fun!
