Looking for a free alternative to Microsoft Office?

I'm talking about Open Office. This isn't a commercial. If you're looking for software to use and don't have the money, or don't want to spend the money on Microsoft Office: Word, Excel, PowerPoint, or even Access, I recommend Open Office.
   It's fully compatible with Microsoft Office. I've been using it for about three years now and have had no issues. It does everything Microsoft Office does, and it's easy to use. You can save your files in Word, or Excel, or PowerPoint formats and take it from computer to computer just as you would the commercial versions of the files. I used Open Office to write and design the covers for all of my books.
  You can get it from www.openoffice.org
  Download it, install it, and try it. There are no commercials, no annoying ads, and no registration required. If you're not sure you want to stick with it, just say 'no' to the option that makes it your primary program for Office files. You can change that later if you like.
