Is there a reason why you're changing the river from the commonly-used "waterway=riverbank" to the rare "natural=riverbank"?

I've reverted the deletion. There's a tool in the JOSM editor to do this, but it's a bit tricky to get right if you're only trying to undo part of a changeset.

Consensus is that unofficial trails should be mapped, but should be marked as "informal=yes" (and "access=no" if people aren't supposed to use them).

See the discussion at osm.wiki/Talk:Proposed_features/Social_path and the linked mailing list discussions for why hiding these paths is a bad idea.

I'm not familiar with the Vespucci editor, but when you're changing the layer/tunnel information for I-90, make sure you're selecting an individual way making up the freeway, rather than the relation that groups all of the ways together into a single unit.

You've turned I-90 into a tunnel across the entire state of Washington twice now. Whatever you're doing, stop it.

Gossard Field still exists -- "Juno Elevator Road" doubles as the runway, the building with the curved roof is a hangar, and the FAA says that five airplanes operate out of it. I've restored the airport node and improved the mapping.

In addition to whatever you were trying to do (your changeset comment of "Fixed building" doesn't resemble your changes in the least), you dragged a node of an island off the coast of Alaska. Please be more careful in the future.

Please don't add fictitious data to the map. It wastes the time of those of us who have to clean it up.

If you want to practice editing, there's a development server you can use: osm.wiki/Sandbox_for_editing

Please don't add false data to the map. It wastes the time of those of us who have to remove it.

Please don't use a "." as the changeset comment. It's not very informative, and it's a pain to try to click on in the history view.

Thanks for your work improving the map!

The usual way to map a school is to place the name of the school on the school grounds, but to not name school buildings unless they have their own, different name (eg. the "So-and-So Memorial Gymnasium").

Actually, I think the problem with the lookup feature is that it tries to be too smart: a search for "parking" does bring up "car parking", but it's mixed in with "car sharing", "charging station", "park", and other things that might or might not be related to "parking".

The other issue is that OSM started as a project to map England, so many of the terms for things use British English rather than American English.

Please don't add fictional content to the map.

Thanks for your help with the map!

A couple of notes:

1) Parking lots should be mapped as "Car Parking". "Parking Space" is meant for the individual spaces if you're mapping a parking lot in fine detail.

2) Please don't attach things such as school grounds to adjacent streets. Yes, I know it looks better in the editor, but if you have to edit the road for any reason, having non-road things attached to it makes it painful.

You've drawn this building as overlapping two different houses. Which one is #9011?

Did you mean to remove the "highway=" tag from East A Street in this edit?

You appear to have forgotten to indicate what sort of thing this is. Mapping a bare address has some value, in that routing software can give directions to it, but it really helps if you add a "house" or "apartment" tag (or the generic "residential building" tag if you don't know what sort of residence it is).

Did you mean to mark a section of railroad as "abandoned" in this edit? The section near the Baird Springs Road tunnel doesn't look abandoned to me, just shadowed by the edge of the cutting.

The "name" field should only be used to give the names of things, not to describe them. It's obvious from the tags that a path is a path, so you don't also need to name it "path".
