How do I get a domain name?
You can register a domain name at a 'domain registrar' of your choice (search Google to find some). We usually use 123-reg.co.uk or 34sp.com in the UK and namecheap.com in the US, but you can use whoever you like. Just make sure they have been trading for some time, have a good reputation (Google can also help with that) and let you control your own domain using a control panel independently.
