Apparently, inviting people from the in-game menu in Burnout Paradise is broken, or just when I invite people it's broken. TVC just told me that the first invite I sent him didn't go to his inbox after the notification disappeared. He had to send a voice message to tell me to invite him again. So if you were "busy" with CG for a little while after turning on your 360, you would've missed it. And I remember checking what you doing after a few minutes, and it just said "Xbox 360 Dashboard."
