Looking for something?
Yes. You can have multiple domains point to the same site or to a directory on your site. When you sign up, just choose the main domain you want to use, and later you can login to the control panel and add the other domains through the addon domains section of the control panel.
Also, before adding on the extra domains, make sure that you have pointed them to the appropriate name servers (ns1.pixelpointcreative.com, and ns2.pixelpointcreative.com) with your registrar, and allow them sufficient time to propogate across the internet.
