Welcome,

I addressed all of Wilmington and Woburn a few years ago. I would strongly recommend learning JOSM and using it instead of a browser-based editor.

Other suggestions:

-Add “access=private” to driveways. -Add addr:city and addr:postcode in addition to housenumber and street -Split multi-unit buildings such as row houses so you can add the addresses to the polygons rather than separate points. For two-family houses where the addresses are above or below each other, you can also add a single address to the polygon but with two values, such as “75;77”
