CutePDF Writer is a free pdf viewer, similar to Adobe Reader, which shows up on your printer list when you try to print a document. This lets you produce pdf versions of documents. CutePDF Pro is a reasonably priced full featured pdf editor, much more affordable than the Adobe product.

PortableApps.com is a project where service-minded people have taken various computer applications and done a combination of compression and other modifications (with proper respect to copyright laws) so we can install them on a flashdrive for portability.

Aside from conveniences, and the fact that "Open Source" free applications have been chosen, there is also the advantage that no modifications are required in a computer's registry - these applications can be run on secured computers such as those in CF's math labs.

I am providing a link to the general PortableApps.com page. You can download the platform only and use selected apps. The Standard Suite includes OpenOffice, similar to other office suites like Microsoft Office, including a word processor, spreadsheet, database and presentation programs. The Light Suite (and Standard Suite) include a free pdf viewer.
