Important note regarding printing

Before printing turn off the optional header and footer information. Also, make the left margin 0.75 in (1.9 cm) and the other margins 0.5 in (1.3 cm) so that the page breaks I built into the pages work as intended.

Some of the files are PDFs and you need the Acrobat Reader available from Adobe. Some files are also MS Word 97 or RTF documents, which just about anyone should be able to view. If you have trouble, try going to to download the Word Viewer.
