Hello Angela, Your wiki page doesn’t describe your conflation process at all. You’ve even left the field in the template blank:
https://wiki.openstreetmap.org/wiki/Import/Catalogue/MassGIS_Addresses#Conflation <https://wiki.openstreetmap.org/wiki/Import/Catalogue/MassGIS_Addresses#Conflation> There are 156378 addresses on OSM in Massachusetts already, and you absolutely need a plan to handle those and not have duplicates.
