Steve,
Open your Microsoft Word, go to the edit button and select all to highlight the complete document. Then hold the CTRL key down and push the C key. This cuts it to the clipboard. Then log on and open your post. Once the post is open put your curser where you want the document to be and hold down the CTRL key and push the V key. This will put all of the text you have highlighted into the post. It is called cut and paste and I have did it with several pages of stuff from Word in the past.
