it may be better to keep the demo site as a reference, and add another site to the same ezp installation. see 'documentation/Installation and Configuration' for different ways to do this, especially:
* Site access, http://ez.no/developer/ez_publish_3/documentation/
installation_and_configuration/configuration/site_access
(url on one line)
* Several sites with one installation, http://ez.no/developer/ez_publish_3/documentation/
installation_and_configuration/configuration/
tips_tricks/several_sites_with_one_installation (url on one line)
when you got that working, start reading the Customization chapter in the documentation: http://ez.no/developer/ez_publish_3/documentation/customization
