Hi, I am trying to register a domain(.com). When I entered my email address in the customer details section, it did not want to go through to the next section which is the payment information. I have a gmail email address. Why can't I use my public email domain to register? I then tried to use a private domain email which i still want to apply for and then it went through although the email address does not exist yet. How can I get my domain registered and verified?
