I missed the putting challenge for Nation when I became a member of Nation, because it was already put for all players by the time I became a member. The only thing I got was sleeve of balls, that lasted about a day.
Nation should be considered special Beta testers that play features or new things to test before they add to the game on updates. Kind of like what POGO.com does with people testing their games before they launch. Just a thought.
Beta testing those only exclusive to Nation members.
