Are you following the osm.wiki/Automated_Edits_code_of_conduct ?

All done! BTW I've moved all buildings according to the "Virginia Imagery Service", which should match the reality better than any other imagery provider.

Hi Glassman,
may you please be so kind to use a dedicated account for your NHD imports?
(and use a different changeset comment for this very changeset!)

It's not a problem, it's just that in any urban ("mapper-dense") region worldwide you wouldn't find this mapping style anymore.
If you are finished with your current mapping I would be glad to fix it for you!

But if you are going to do more stuff in your current editor session I will wait, otherwise I could cause edit conflicts.

Hi dmich,
you are doing the hard work in OSM!
Is there any specific reason why you snap the retail landuses to the street (Carrollton Pike)?

Dear mulalinda,

please try to straighten buildings which have right angles by pressing "Q" on them before upload.
An option is using a better editor like https://josm.openstreetmap.de/

Kind regards

Mixing in the "Central Europe Pipeline System" edit wasn't so good.

Why have you changed the Wikipedia link of the "Upper Potomac" to "Potomac River" relation/2637000/history ? Seems wrong to me.
