In Sites & settings, you select whether to host multiple websites. You also select the global organization tasks and settings that apply to all your websites. And you select site-specific tasks and settings for each website that you host.
Warning: We strongly recommend that you only assign full Supervisor rights for Sites & settings to a select group of users. General users should not access this section of the program because changes can affect multiple web pages and sites. Only users knowledgeable in all areas of website creation and publishing should perform tasks in Sites & settings.
