The Chosen One
David's right, your agency should be helping you out. PM one of the Officers or the Director if you are unsure what to do. Communication is a must in ANY agency, so please don't hesitate to ask your fellow members. No question is stupid and I'm sure they will be more than happy to assist you and help you grow.
Many agency Treasure Hunt the same way but have different ways of keeping them organised and such.
Also read up on your Agency Message Board daily for any new Treasure Hunts you are on. That will tell you who you need to do a favor for.
