I saw that there are websites to buy bulk upgrading tools and such online on Hay Day. I was wonder if we could set up Hay Day trading on JSP? Also, is there any good way to finding other peoples' farms besides game center? I'm on Android so I don't exactly have game center.

anyone? we could establish

fg:item prices
fg:coin prices

stuff like that

hardest part, as far as im concerned is figuring out how to add people manually through game center or google+ or something
