I just got an Xbox 360 Elite a few days ago and started playing offline. I have had an Xbox Live account for a while now (I created it before I got my Xbox 360). Now that I have the Xbox Live cables all hooked up, I want to sign my profile on my console (which doesn't have online) to my Xbox Live account. However, I don't know how to do it (I think I saw something about doing that a few days ago, but I forgot how I got to it), please help!
