This is no big deal, but you can use the Project Gallery as a standalone application. Instead of having Word, Entourage, Excel, and PowerPoint in your dock, you can just have the Project Gallery itself.
You'll find it in the Microsoft Office 2004 folder, then in the Office folder. It's called Project Gallery Launcher, and it even has the nice Office "O" as its icon. This can save dock space and let you have access to all the Office programs and use that nice O in your dock. This only works with Office 2004.
