@Bremen haven't looked into it yet, I was out of town at GDC @juannn91 the tutorial is for iOS with CoconJS... do you know how to adapt it for WP or Android?
@gfigueroa I did get @stctr 's tutorial to work on android, I don't have a IOS developer account so cant help there. But it does post scores to facebook from android. I can't try to help you do it if you need any. I haven't tried juannn91 tutorial.
