True Site™ Enrollment
Enter the top level domain for your True Site™ registration. Any lower level domains will automatically also be registered, so it's important to register the highest level domain you want to use. For example, if you wanted to use True Site™ on the hosts www.supralink.com and webmail.supralink.com, you should register supralink.com as your True Site™ domain.

Example: If your URL is http://www.supralink.com/, you would enter supralink.com.
