rules to play paragliding

When entering a thermal, turn in the same direction as other pilots already in the thermal. All pilots in a thermal should be circling in the same direction. It is easy to watch other gliders circling in the same direction, but dangerous if there are gliders circling in oposite directions. If I am ever in a thermal and see any glider other than myself circling in the oposite direction, unless there are only two gliders, I will leave the thermal. If I notice another glider circling in the thermal and we are the only two in the thermal. I will switch directions to match the other gliders direction.
