At the Wordpress Home page, click on the Get Started button to begin creating your blog.
Next, you'll be asked to sign up for a free account. The sign up page is very simple and you only need four things:
1. Email
2. Username
3. Password
4. Blog address
Wordpress will automatically create your username and blog address after you type in your email. The blog address can be changed. Keep in mind, the blog address will match your blog name and it should be easy to remember and one that people will find when searching the web for your blog.
Be sure to select the option for the free blog address. Once you've done this, click on Create Blog at the bottom of the screen to continue.
