When I receive gifts from friends, some of them have a "THANK" button. What does this actually mean? How does a friend get thanked? Does the "THANK" only come with being given Collection Items, or what? Or does the friend get thanked by automatically being given an item? I often notice my elements missing and not sure where they have gone! Please help...
