14 people showed up to learn how to use JOSM to import addresses into OSM. The training ran from 1PM until 4:30 when most everyone adjourned to the pub up the street.

I added the addresses in Hunts Point via JOSM in the evening after the training, then drove around the neighborhood the next day with my iPad verifying everything. The address data was perfect but several previously tagged street names needed fixing. Overall very easy and straightforward.
