I've always run the server on "host.example.com" and just left "example.com" alone (the default construction page comes up). Now I'm thinking I want to use "example.com" to promote the business and increase my visibility, but running a website, and all the apps that will come with it, as the Admin user doesn't seem like a safe idea. What would be the safe approach to using the domain name to host a website/services? Should I create a normal user and assign "example.com" to them, but leave "host.example.com" assigned to the Admin user (I assume that's possible)?
