The geoTips are established on an optional basis, so each geoSpotter can choose to give, or not to give, a geoTip to the geoHost. Nevertheless, we strongly encourage each geoSpotter to thank the geoHosts in this way that we think is adapted to everybody's individual means. The geoHost offers his private land and allows you to enjoy a privileged spot, so it is fair to thank him by a geoTip.
