I wanted to pass on a new site that I found which is the Office Templates blog: http://blogs.msdn.com/templates/
One of the things I never really understood before coming to Microsoft was the power of templates and how well they worked. I saw people with great looking documents and I never knew how to get them myself. Now with Office 2007's new templates as well as the great templates on Office Online I think some of my documents look better now. That being said I wanted to pass on the Office Templates blog as well as point out a holiday templates contest as well (this is over now, sorry) . Check it out!
