When we talk about creating a website, what we are doing is making a new website that exists within the root folder of your original website. Although the website will look to a user like a separate web site, it will actually be a section of the main website.
The Add New Website Wizard makes creating a new web site easy for users of any experience level. The wizard will walk you through creating the site step by step. To access the wizard, go to the Control Panel. Click on the Add Site button in the Control Panel window.
