Currently I am using the "Enable Multi-Site" plugin for creating new wordpress sites using wildcard sub-domains. It works fine, however, I would like to be able to use domain names instead of sub-domains. So if someone were to create a new blog of their own, they would have to fill out their "domain.com" and after clicking "Create Site" automatically creates their new blog under the domain name they told it to point to without me having to touch anything. My goal is to have this feature be automated.
Is this possible? If so, how do I set this up?
