That’s what I said. Please read the posts in the “Building Your Website” post before this one and your life will be easier.
A Domain Name is the actual name/location of your website. For instance:
PatrickKhayler.com or .net or etc.
Can’t I have anything I want?
No. If it’s already used by someone else you have to use something else. This can be a big problem if multiple variations of your name are already registered (remember the pen names post? I told you to search hard for this reason) for instance, PatrickKhayler.com was available but what if it wasn’t and PatrickKhaylerAuthor.com, PatrickKhaylerNovel.com, PatrickKhaylerBooks.com etc. are also already gone. What are you going to use? In other words think hard early.
How do I get a Domain Name?
You have to register one through one of the big providers. I used http://www.godaddy.com. It was very easy but, like WordPress, I haven’t used anything else so I can’t comment on those sites.
You go to the site, log in and search for what you want, if its available you can purchase it for 1-5 dollars a month. If not, you have to pick something else.
Don’t search until you are ready to buy. If it is available it will be gone soon and people scan the web for people searching registers. They will buy your name first so you would have to buy it form them (expensive). In other words don’t sit down to search registers until you are ready to purchase and have a credit card etc. It’s cheap now but doesn’t have to stay that way.
