How do you send videos to Halo Waypoint?!

Just saw a tweet saying send your videos to the gamertag “HaloWaypoint” But I see no such option anywhere in Reach or on XboxLive to send videos. So why? Why tell us to send videos and then not tell us how?

Halo: Reach actually makes this quite a bit easier for us. Now all you have to do is tag your videos with “HaloWaypoint” and “Top5” without the quotes.

Of course, you can add other tags to make them easier to distinguish based on topic or theme.

Looking forward to see your awesome.
