How do I host an additional domain name under my account?

• Domain Redirects - Customer owns customer.com. Later they want to add customer.net and customer.org to their account. Any web visitors going to the customer.net or customer.org site will be directed to the customer.com site.
• Domain Child Account - Customer has a friend who wants a small website. Domain Control Panel will allow the customer to create a new child domain for their friend. The friend's domain is an independent website. The friend may login to their domain via ftp and change files themselves. The customer also has full control over the friend's domain. The friend may ONLY control their child domain, not the customers.
• Seperate Account - Customer wants to start another domain completely seperate from their first original domain. Basically, just sign up twice. User will then have two seperate subscriptions to Gigfoot. Either one may be cancelled independently.
