I believe that if you only have your computer (online line rider) or only have your DS (Line Rider 2 Unbound) than you should be able to send tracks you made or tracks in progress between the two. So if you were on your DS, and you know that many people cant gather round a DS and watch, then you could send it to your online line rider profile. And if you were working on a awesome track on the internet line rider, you could send it and work on it on the go on your DS!
I dont know how to explain this better so I am sorry if this does not make sense!
