I think what you are asking is how to create a pdf file from a document, not how to attach it.
There is a free tool that will create PDF files from almost any printable document. Go here to download it:

Cutewriter requires a converter such as Ghostscript that you can download here:
http://download.cutepdf.com/download/converter.exe
Install the converter first, then the cutewriter. Then open the document you want to convert, select "file", "print" and select cutepdf as your printer. A window will pop up asking what you want name your new pdf file, type in a name and click save. Then you have a pdf file you can attach to an e-mail. :wink2:
