Science Department head at Red Bank High School - have lead students at RBHS in OSM mapping since 2010 and have been hot team for three years. this has lead to the development of a state approved course in GIS/OSM in 2014. ( I am frequently kidded about the lack of edits that I contribute, but try to keep a watchful eye on new OSM ( 25 at a time) High school students and see how much editing you do. I have taught well over 500 + students to use this software and be engaged in mapping.
