I thought of a great social idea for Halo 5 and the MCC as well. Some of us probably all of us have many 50 plus at least I say over Xbox that all play Halo. Why not implement a feature if your trying to get a group or custom game going have a bulletin where you could post so all your friends can see your message so you don’t have to message people individually or send party chat invites to everyone. I know you can send a message to massive amount of people but as we know the Xbox tends to lag when you send a mass group message out or it doesn’t go through. My example of this is I host a lot of BTB custom games of Halo CE in the MCC it would save a lot of time if you could just post a bulletin for all your friends to see hey I’m doing this game A for example at this starting time. What’s everyone’s thought on this?
Great idea,spartan! 
I wish! Would make company game nights much easier!
