I thought I'd done it but when I try the links above they don't work so it doesn't look as if I have. I bought both the Domain names from Net Benefit.
When I set up my own site I don't think I did anything other than buy it and then upload it to upload.ntlworld.com with Terrapin, using
www.higgsofhambleden.co.uk as the site name and it's worked perfectly ever since.
