OGA is recruiting, mainly to build up a community of mature Halo players to play more custom games together until they fix matchmaking.

If you are looking for people to play custom games, and are at least 18 years old and have a working headset, look into our community.
We do not like inviting every person on XBL into our custom games, so we made a community just for it so we can control who we are playing with.
