New User Register

When a new user goes to my main site and register it does not show on my admin panel that they are register on the main site, only on the network. What do I do? I want to create a network of sites. but as of now I have to manually go in and send an invite for them to join each site. I am trying to make it as simple as possible to allow authors. I do not want to do this manually each time. I at least want the people to register for the correct site: http://cjgroove.com
