Ok, you need to buy some web hosting first, I recommend UK Web.Solutions Direct, our website is hosted by them. Next, you need to buy that domain from someone, I personally have only used GoDaddy, and they are great. When you have both the domain and web hosting account, and they are linked together (by adding your host's name servers to the domain), simply upload the files via FTP and you are done .

Alternatively, I could just set you up a subdomain, e.g. http://warmachineclan.atkcommunity.com/ , although you could simplify that to http://wmc.atkcommunity.com/ . I would set you up an FTP account, and also give you a subforum on our clans part of the website. I am also willing to give this away for free, providing you link to us on your website.
