How Can I Change My Site's Address or Domain Name?
The address of your site can be changed at any time via the Settings tab in the editor. Open up the Settings tab and then click the "Change" button connected to the Site Address.
Use a Domain You Already Own. If you've previously purchased a domain , and are not using it with another site currently, you can enter it here. You can also use this option if you bought a domain through another registrar and want to use it with your site. Your domain must be configured to point to IP address 199.34.228.99
