Domain If choosing ltd.uk or plc.uk, ensure the domain matches the registered company name. Eg, Cyberstrider Internet Limited can only have cyberstriderinternet.ltd.uk or cyberstrider-internet.ltd.uk (These are manually checked by the registry, and will be rejected if incorrect information supplied) Username Choose a username that contains only A-Z or a-z. If your desired username is already in use we will change yours slightly before allocating it to you. E-mail Provide us with a valid email address that we can forward all email to from your new domain. If you have ordered a package containing POP3 mail, then still provide us with a current valid email address to forward to as you will need to activate the POP3 mailboxes after your service has been set up.
