Word Web App lets you share your documents by sending a link in email. When people click the link in your message, your document opens up in their browser, so they don't even need to have Word to read it..

All you need to do is upload your document to SkyDrive, and then sned the link to people you want to share it with.

Take a look at the newsletter template in the Word Web App. If you like what you see, download it (look for the Download command, next to the File tab near the top of your screen) and open it in Word on your computer. Now make it your own by adding stories and photos from the past year.

When you’re ready to share it, click Save & Send on the File tab in Word 2010, and then click Save to Web. Use the Sign In button to sign in to your Windows Live account.
