NOTE: Because there are so many operating systems and application software, we're using the Adobe Acrobat "portable document" (.pdf) format for many of our documents and forms, so that everyone can view and print the files with all the formatting intact. If you don't already have it, you'll need to download the FREE Acrobat reader software. Versions are available for Windows, DOS, Macintosh and various Unix platforms. (This software is simple to use!)
