Does anyone know anything on this site, and is there anyone here who is currently a member of this site?

Apparently you can only join if you have been invited by another user, even though it says on their homepage that you can register for free. But when I have tried to put my details in I haven't been able to get very far.

This site is meant to be very good for marketing opportunities and for networking, if anyone who uses please invite me and let me know how I can sign up to the site.
