PDF Software
Do you need to create PDF files so that others can read your documents without having the latest versions? Try PDFCreator.
It installes itself as a printer. You then "print" to the
"PDFCreator" printer which allows you so save anything as a PDF file.
PDFCreator is also available from http://sourceforge.net/projects/pdfcreator. Alternatively, if you have Office 2007, you can save documents as PDF files directly.
