If you are following Google you know that several days ago a new link appeared on the top right side of the page for New Features.  Google Docs has added templates.  There are over a hundred for each application and address multiple needs.

I threw together some screenshots on a newsletter template and saved it as a PDF file for you to see, but I say just go there and play around.  You can save a template under a new name and customize it with your company logo.  You have multiple choices for how to save your new document.  At this point you have to click on the new features link to get to the templates but I am confident that the Google folks will incorporate the templates into the document tools menus soon.

Addendum – I spoke too soon (or too late LOL) If you sign in to Google Docs and click new you can now choose document, spreadsheet, presentation, folder, or FROM TEMPLATE!! Yay Google!
