There's a great little free program that will turn your Word documents into pdf (portable document format) files, available at: http://www.primopdf.com/.

Why would you want to do such a thing, you ask? One reason is to preserve the formatting of your Word document when you send it somewhere else by email, CD, the Web, or whatever. When you put a document into pdf, there's no danger of moved margins, altered fonts, or skewed headings when someone else opens the document on their computer. Also, it prevents people from copying, changing, or otherwise messing with your work--well, they can still do that, but you make it a lot harder for them.

The PrimoPDF program, although free, doesn't come with any ads or aggravating pop-ups, and no registration is required. Cool stuff.
