12. Where can I buy a domain name for my site?
Domain names can be purchased at any accredited domain registrar. A domain registrar is a company whose main purpose is to register domain names for people. Most hosting providers can also obtain a domain name for you, but domains can be more expensive this way, due to the added overhead.
There are several very popular domain registrars, including godaddy.com, namecheap.com, and dotster.com. Most of their prices should be about the same.
