How can I register a new domain and use it with a site hosted on BC?

Hi Taylor3d,

In order to add a domain to your site, please refer to the following document for instructions: http://helpx.adobe.com/business-catalyst/partner/going-live-guide.html. To summarize, once the site is live, simply add your domain to your site via the admin console > Site Settings > Site Domains > New Domain. At your registrar where you purchased the domain, you will need to update the nameservers to the ones listed in the article I've just provided.

In regards to using Business Catalyst for hosting email, you will need to upgrade to the webBasics+ plan. To do this, within the admin console navigate to Site Settings > Site Management, and the ability to upgrade will be present. Once your site has been upgraded to this plan, you will be able to add email accounts via Site Settings > Email Accounts.
