If you want your domain to automatically send visitors to another domain, you can use Domain Forwarding.
Scenario: The owner of mywebsite.com sets it to forward visitors to myotherwebsite.com. When someone types in mywebsite.com, they are forwarded to the other Web site, and myotherwebsite.com appears instead.
To set up domain forwarding, log in to ControlPanel, go to Domain Names > Domain Forwarding, and enter in the address that you want to forward your domain to.
