I can't remember how I unlocked their client orders and my friend has started playing. Help?

@DezDarkly i believe it was after doing one of the difficulty cap client orders and then "talking" to them.

Thank you I will let him know.

Some COs require talking to the NPC that gives them first before you're allowed to take them, even if they don't have the CO icon over their head. I believe the Summoner NPC requires you to talk to him as a Summoner.
