Hey there Nat,
Thanks for helping out with my golf cleanup maproulette challenge. One thing to note is that the green and fairway shouldn't share nodes when the fairway fully surrounds the green. There should be a fringe that is left so that there is a gap all the way around the green. Of course, if the fairway doesn't surround the green, but instead butts up against it, then yes, by all means share the nodes between the two objects. Thanks again!
