I've used WordPress before but only through the website. This is the first time I've actually installed WP and I'm loving all of the customization options that are available to me now.
I'm a bit confused about how to actually make my blog accessible to the public though. I'm working through MAMP on Mac OS. Under wp-admin, the WordPress Address and Site Address are both set to
http://localhost/wordpress. I'm aware of this link but I'm not sure I'm following.
Should I leave the Site Address at localhost/wordpress and only change the WordPress Address? Also, if I want to create the url
http://test_site.wordpress.com, for example, do I have to make an account with wordpress.com for that URL first? And does the username and password I created when installing WordPress come into play at all?
