For those working on there CAS application right now: You can download a 30 day free trial of Adobe Acrobat 9.0 Pro here:

This will enable you to save your application file and distribution list along the way, and will also give you some advanced features and options for fonts. Your options are much more limited if you only use Acrobat reader for processing your CAS applications. (Note: I don't think you need the Pro extended version, Pro should suffice)

I hope this is helpful to some of you. It has helped me a lot.

How do you change the font on CAS application with Acrobat Pro?
I tried but being a dinosaur I am I gave up soon after.

When you're in the program look at the very top of the screen where the menu selections are. Select view-->toolbars-->properties bar

Now you will see a toolbar towards the top of the screen displaying the font type, size, justification, etc.
