That message means it's already square.

Hello.
Please be care not to delete unrelated tags. In this edit you deleted "height=16.8" tag which belongs to the building here.

Yes, I was referring to York Ave. Bing imagery might not be the latest in that spot. around NYC Esri have been a bit newer, although I hear Bing should update theirs soon.
You can also use Bing street imagery but it's from 2021, I don't know if the situation there changed since.

Hello.
Please don't map sidewalks a single loop around the whole block. Each street should have sidewalk as its own way.
Also, please position curbs cuts exactly where they are, not just randomly at the corner of 2 sidewalks.

Hello.
How come you tagged all these intersections as uncontrolled when they are clearly have traffic lights?

It's best not to use just naked url= tag as documented on url=*

No, that's Q in iD/RapiD and even JOSM.
Osmcha is just for reviewing, not editing.

Hello.
Please split your edits by geographic regions. Group them by neighborhood, city or county at most. There's no need to have a single cross-continental changeset.

When mapping rectangular features, you right-click on them and select "Make Square" (shortcut key Q) to straighten it and make it have right angles. That makes your mapping look neater and feature closer to the real world shape.

Hello.
You tagged these buildings as semi-detached, however that is most definitely incorrect. They are townhouses, aka terraced.

Hello.
Please note, when adding address, street name must be fully spelled out. "West", not W. "Street", not St.

Hello.
Rather than outright deleting features, it's much better to update them to their current state. Doing that not only keep this address searchable, but also preserves history if this object, which can be useful to refer to in the future for whatever reason.

OSM doesn't have a different elements for lines or areas. It's just assumed that certain closed ways with certain tag combinations are treated as areas.

It sounds like it'd be more reliable/durable if you'd look into figuring out what your code is doing wrong rather than having to edit OSM data, because this becomes borderline osm.wiki/Tagging_for_the_renderer

Hello.
Did this new business keep the old place's phone number?

Hello.
You tagged this road segment as having 4 lanes, but looking at the satellite imagery, it seems to be 5 or 6, depending on the spot. Is that not correct?

Hello.
Could you please elaborate on those pickleball courts you added? I don't see any of those features in the satellite imagery you use or any available satellite imagery.

Is this actually a cultivated garden or just grass with a couple of trees? Would landuse=grass be more appropriate?

I fixed it in https://osmcha.org/changesets/145629828/. This might need a couple of minutes before you can see the actual changes.

If a feature doesn't have a website then it doesn't have a website. Nothing can be done about that.

🤨
I didn't deny any history! I never said it's not important! That's completely out of line for you to say that!!

This is OSM. This is this is a maps database. This is not a place to teach people about history.
There's a right place for everything, but OSM is not intended to be a history lesson resource.
