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".

That does not look particularly park-like in aerial imagery, and the Pullman parks department is unaware of any park named "Egg Park", or of a park by any name in that location.

Thanks for your work in mapping the less-populated parts of Idaho.

OpenStreetMap measures elevations in meters, not feet, and lets end-user software decide what units to display it in. By changing the numbers for Stevens Peak, you've made it appear to be the tallest mountains in Idaho.

(I've changed it back.)

For future reference, the correct tag for a parking lot or parking garage is "car parking" (amenity=parking). "Parking space" is for if you're mapping the individual spaces within a parking lot.

In general, we don't record the ownership of private residences on the map.

What was the assignment, to vandalize the map? I believe everything in this changeset has been deleted as having no basis in reality.

Is it really called "Short Pointless Path"?
