Halo Reach Community Made Maps for Matchmaking

I was looking around on the bungie.net forums to see if there was an area where I could submit a map for online multiplayer and I read that after June 17th 343 was taking over and Bungie won’t be considering anymore community made maps for matchmaking. So I came here hoping for an answer. I worked hard on my map hoping that it may one day be in the action sack playlist.

Here’s a link to a screenshot of the map: http://www.bungie.net/Stats/Reach/FileDetails.aspx?fid=19809245&player=Abnormal%20Zombie

If anybody could help me out I would greatly appreciate it, thanks.
