Go on network settings and go on which ever channel you want to go on but make sure all of your freinds are on the same channel.(this is on the bit where you turn it on and you have your screen)then go to the online gathering hall and somone should start a qeust but dont leave on your qeust wait and it should come up with his or her name go to the board where the lady sells items and look on the board it should say hunting quest or treasure hunting quest level 1 2 3 4 5 or any of the missions available in the old man quests,then wait near the table and look around the gathering hall and you should see a person with his or her name above his or her charector.
