Trade with players using the board/truck
I don't know if this idea was already suggested but, I thought that would be nice to have some trade mechanism using the truck.
Someone from the player's facebook friend list could request some items through the board, choosing the desired items and the price they are willing to pay for it. Once the player gathered the requested items the truck would deliver for the requester.
I don't know if there is a similar mechanism once you unlock the neighborhood, I'm at level 19 yet. But it would be interesting and safer... more interesting if avaiable in early levels.
Sorry for the bad english.
