By default your chat room works as soon as you paste your code onto your web page. To make customizations to your room there are 3 different ways to make these settings.
Site Wide Customizations will be reflected in all the rooms within your site and will over write any server default settings.
Room Manual Customizations will only be reflected in the room you are making the changes to. This setting will over ride any server default and Site Manual Customizations.
3. HTML Applet Code Customization
HTML Applet Code Customizations will only be reflected in the room you are making the changes to. These settings will over ride any server default, Site Manual Customizations & Room Manual Customizations. This option will allow you to have the same room on 2 different pages with a completely different look and feel.
