Dances With Clouds:
I was around AFS the time that the guy behind the whole master switch ordeal was. He did train as an instructor (not sure if he finished) but was given his marching orders before he ever made it onto the payroll. He then went to another school and then to another then a long time later I read about his incident that got him banned from AFS in the news to no surprise.
