I have to agree with Kim on that one, if someone has a "wiz" title, regardless, they're sort of viewed as administration in some way.

But, an alternative might be to have a questing NPC, where and admin could make a quest, have the NPC verify the quest's completion. Let's say there was an area that was made for a quest, and you needed to collect an item from some boss or something of that nature. Presenting the NPC with that item, would let you complete the quest. Maybe each player can complete the quest once or something, but for rewards... I dunno, I always thought questing was for fun \:\)

If rewards were given, people in this case, would just do the quests for the rewards, and everyone would get the same rewards.
