[Talk-us-massachusetts] Missing and unnamed streets

[Jim Snyder-Grant]

I'm a bit rusty in OSM, but I know Acton well, and I can deal with ODS
spreadsheets in LibreOffice and SHP files in QGIS.  I haven't followed all
the technical detail, but I'd be happy to help.

I think my first task is to look at the Acton streets listed in
 https://mega.nz/#!TxlABapS!4MNK5R4UQEkeLjj1pNISufQMNgGs2Vl1YvLGFU4RU3A
and evaluate them.

What do I do next?

If the street exists, and I can reliably locate it, I can add it to OSM. I
just did that for the new "Cindy Lane":
https://www.openstreetmap.org/changeset/61694902#map=17/42.44630/-71.43720
Are there particular tags or changeset comments that would be best to use?
(This one was particularly easy to locate, as the building at 1 Cindy Lane
is already in OSM, and the street is already in Acton's online GIS at
https://actonma.mapgeo.io )

What should I do if I determine that a name in the spreadsheet is a
mistake, either a misspelling of an existing street, or a street that
doesn't exist yet, or what?
Is there a place we are recording the disposition of streets?

Sorry if this has already been covered. I've had a bit of eyes-glazed-over
at the awesomely deep and careful technical comments.
