The purpose of this demo is to help you become familiar with ATG 2007.3 functionality by showing you many of the same features that you would use in a real ATG 2007.3 site. As you begin to learn the system, you might want to use the demo to test your knowledge by altering some of the pages it contains. If you do this, make sure that the modifications still permit the demo to run. For information on general configuration changes you may have to make to support your modifications, refer to the ATG Installation and Configuration Guide.
