Social Go is a real website, I googled it. It looks like another site like Ning where your website is on the same domain as everyone else's. They do have the option to pay to have your own domain though.

SocialGO offers 2 premium levels of service. SocialGO Premium for only $24.99 per month gives you all our great features, loads of bandwidth and storage and the ability to use your own domain name. Start a 30 day FREE Premium Trial Now.

If you want us to do that hard work for you, check out see more the SocialGO Concierge Service where we design, setup and configure your network for you for $149.99 per month.
