I want to do your exercises offline.
That is no problem! We have provided printer friendly copies of all of our exercises
that you can print and use offline. The exercises are available in two paper
sizes. You will need the Adobe Acrobat Reader, which you can download for free.
I want to sign up for your newsletter.
That is great! We publish our newsletter once a month. It contains highlights
of web site changes, and some special articles that you can only find in the newsletter.
