If you signed with our service and already have a domain name you will need to go to the registration company that has registered your domain name and ask them to modify the DNS "Domain Name Server" to point to our server below. 

You can look up and see what company has registered your domain by doing a Domain Search and than click "show me who-is output" button after the search, you can also find out when your domain name expires.
 

Once the domain is registered, it will automatically forward to our servers. Some registration authorities require that the domain be fully configured on our name servers before they will register the domain. For this reason, we suggest you wait 2-3 days after you place your order.
