no one has ever brought up this topis in any forum. i assume i'm just a complete idiot. but i need to kno how do you share maps online with the 360?

Once your map is published you go to multiplayer mode and select the create match option pick the map(s) you want to play, game type and whatever other options you want and then create the game...Then just invite your friends or wait for people to join your room before you start the round!

If you need any help with map making check out www.genesisdevice.org where you'll find some great tutorials!
