OpenOffice.org can directly save documents as PDF files. It's a free open-source Office suite that contains apps comparable to Word, Excel, Powerpoint etc. It can also open and save files in the Microsoft Office formats. Give it a try. See if you like it. http://www.openoffice.org
If you're looking for a standalone PDF converter, try searching Google for "Free PDF writer" It came up with a lot of results, but I can't recommend any particular one, since I've never used any of them.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
