Alright i use 1 profile on my xbox 360 to get achivements and i was wondering if there is anyway to somehow put this profile into my xbox live profile so it has the achivements as well....

When your signed in on profile one, it will give you an option somewhere on the dashboard to subscribe to live, that's the only way.

My GT is MikeC26 if you have any more questions.
