It takes a loooooong time to build a membership... like esteem said you better get something awesome because why would anyone want to join a new site that is exactly like millions of other sites. Oh and I would seriously reconsider your domain name.. firstly no one is going join a site that is trying to copy another major site, and secondly Google is going to be a MAJOR source of your traffic.. but they are goijg to deindex you when they see that name.
