Hello Jlapto,
It depends on where you have placed your web files. If you placed your website files in the public_html folder, then the website name you specified (the primary domain for your account) will be the website name that is used. If you want to use ANOTHER domain name, then you need to create an ADD-ON domain by going into the Cpanel. The folder that is created (it will be created under the public_html folder) will be the location you want to publish that site's website files. IF you are trying to CHANGE the primary domain that you specified when you purchased the account, then you need to request a Primary Domain Change from you live support (or reply back to this post and we can email you email form/notification that is needed for this to be done). A primary domain change is performed by the live technical support team (available 24/7).
Here are a few tutorial articles on how to publish, if you need it:

If you have any further questions, please contact technical support or leave a comment at the bottom of the page.
