Hlao 4 File Share

Does anyone know if the Halo 4 file share is up yet? And if yes, where can I find it?

It’s getting stupid now. I just want to share my CREATIONS and download others work!
Why isn’t this -Yoink- up yet?

Exactly! I just hope 343 implements it soon. Also implementing Halo 4 on the Halo Waypoint app for Android would be nice.
