Your site is already published by default, meaning that it's available for the public to see. If you'd prefer, you can unpublish it while you're working out design and content decisions and then publish it again once you're ready. Your website can be edited both in its published and unpublished state. It's all a matter of preference.
1. Click the green arrow in the upper right corner of the editor interface to access your Account Portal.
2. Your published sites appear on the left, and your unpublished ones on the right.
(A) To unpublish a site, click the green "ON" button on the bottom right corner of the published site tile.
(B) To publish a site, click the gray "OFF" button on the bottom right corner of the unpublished website tile.
With a paid website subscription, you can publish your website on a custom domain name like yourbusiness.com instead of yourbusiness.pagevamp.com. To register a custom domain, see this tutorial.
Note: If you have a paid subscription for a website, then unpublishing that website will not cancel its subscription. To cancel your website subscription and to avoid getting charged for the website, you will need to contact firstname.lastname@example.org
