PDF File Creation Tool for Word Users
Regarding PDF creation, this option is available in Word 2007. All computer labs should now have Office 2007, and students can get a copy for themselves for free (or cheap if they want the media) from here: http://www1.umn.edu/ucs/Microsoft/ms4students.php. There are other freeware programs out there that do this too, but the built-in on from MS is probably the best.
