If you don't have the Microsoft Office suite, and if you don't want to pay a lot to get it, then try an alternative that is great, and compatible with most of Microsoft Office, and best of all is free. It's called
OpenOffice, and you should go to their site and read all about it, or click this link:
http://why.openoffice.org/why_great.html. OpenOffice also does a lot more than what the Microsoft Office suite does, so even if you have MS Office, you may want to check it out. If you do, please let us know what you think of it. I love to hear your thoughts, specially on free software.
