Marty, good looking board!
You probably already know that at the Settlement Trading Post in the back right corner (near a rear door) is a pin trading board on the right hand wall that Cast Members will open up and trade with you from.
My DD was a Cast Member this past spring on the College Program and started collecting pins while she worked and visited the parks. One night during a visit she, DW, and I went to the Fort for a 50% CM discount at HDDR and after it was over we hit the Settlement TP. DD saw the board (big maybe 3' x 3') and trading taking place and was mad at herself for not bringing her pins with her to the Fort.
She is intense about this subject so I figure the next time we are back she will take her pins and do some trading.

PS - the pin case has folding doors on each side to cover the pins which are in a type of shadow box. I'm not aware of a similar box at the Meadow TP. So next time you are at WDW, take the family with their pins to the Settlement TP. I had no previous idea this existed.
