Sounds like you done good, ungy. I like the way you summarized our goals.
To draw money from the World Builder, select Enter World Builder from the in-game menu. Select one of our cities then select the icon for city management (I can't remember which one exactly). You'll see an entry field for gold in the treasury. You can type 5000 in the field, then exit the World Buildier.
We should proably start keeping track of how much gold we draw from the World Builder so we don't go over 100,000.
