I am new to DF and I have only played a few games. In my latest game, I am trying to trade with a caravan for a new anvil. However, there is a problem. I can't appoint a Broker. In my other games, I started out with a Leader and a Chief Doctor. The Broker skill was always available for when I chose to appoint one.
When I go to the [n]oble screen, I just see the expedition leader. There are no other positions on the list; not even the Chief Doctor.
Any idea why this is?
