If you already have a domain name registered that you would like to use, there are essentially two options:
You can retain control of the domain yourself in your own registrar account & make the changes to the domain set-up that are required to point it to our website hosting.
You can transfer the domain to us & we will take care of the set-up for you (this is the easier option for most clients). If you do transfer the domain to us, we will be happy to transfer it back to you at a later date if you decide to leave (but we'd hate to see you go).
