Your new domain has been added to your web hosting account
If you are seeing this page you will want to contact support for one of the following:
Add website template to your new domain and build a website completely separate from your original website.
Add a redirect to your main site: such as pointing a .net or .org version of your domain to the .com version. Then you only have one website to maintain!
Or just start building your site using your favorite editor and upload the files via FTP.
