If you're looking for a free office program so that you don't have to spend hundreds on Microsoft word check out OpenOffice.org. This is an entire suite full of tools that rival Microsofts total office package. It is capable of saving, opening, and editing .doc files from Microsoft Word and files from OOO Writer can be saved as .doc type files and opened and edited in Microsoft Word. If you can't afford Microsft Office, don't want to spend the money, or are just curious you should download this and give it a shot. I think you'll be impressed.
