Why does he wear the mask!?
You can load the creator from the online menu in a public session. Press start/options on your controller select the creator from the online menu. Once the creator finishes loading hit options/start on your controller, navigate over to the online menu and choose the option to play online. You will have the option to start friends only and invite only sessions as if you were starting up from offline. You can stay online indefinitely with this method and loading in and out of lobbies and the creator is relatively quick.
Edit: Here, I just made a video.
Thanks!
