Please don't abbreviate street names. It's easy for a computer to convert a word to an abbreviation if it needs to save space, but it's very difficult to go the other direction. (For example, should "St" be expanded to "Street", "State", or "Saint"?)

Could you please pay attention to the changes you're making? The "band" tag on node/1825813421 wasn't an error (it refers to a radio frequency range), while the value for the "phone" tag that you changed to "contact:phone" on ways 161636552 and 256877327 had the meaningless value "+1-"

The usual ways to add addresses are to either trace a building and put the address data on it, or add an isolated point and put the address data on that. I don't know how map software will handle addresses placed on the ends of roads.

If I'm understanding the meaning of the "County Road" tag correctly, I think the best thing to do would be to use the "ref" tag with a value of "CR ###", similar to how state highways get "ref" tags such as "WA 21".

Some of the hotels you've added are on decidedly warehouse-looking buildings. Are you sure you've got the locations right?

Naoliv, I'm pretty sure the app in question is "Pokemon Go": it doesn't spawn Pokemon on school grounds, but it does spawn them on meadows, grass, forests, and sand -- or in other words, exactly the detail that Darth_Vader has added to Carolina Springs Elementary School.

iD has a built-in function for squaring up the corners of an object to the nearest 45-degree angle: either hit the "S" key or right-click and select "Square" from the menu that appears. I don't know how you'd use either of them on a tablet, though.

You don't need to put descriptions such as "home" in the "name" field -- it's obvious that a building is a house because it's tagged as such.

Is Dart-Lo a public park, or a private youth camp? (I'm not sure how you'd tag the latter, but calling it a "park" would be misleading.)

In case you haven't already noticed it, the "Esri World Imagery" for Spokane County is far sharper than the default Bing imagery -- it's detailed enough that it should show things like the cemetery fence.

In case you haven't noticed, you can change the background imagery you're using by clicking on the "background settings" tab (the one that looks vaguely like three stacked sheets of paper). In Spokane County, the "Esri World Imagery" option is much sharper and better-aligned than the default Bing imagery.

Okay, thanks for the confirmation.

Thanks for the addition!

In my experience, actual speed limits on offramps are rare. Is this one a legal limit (a white sign), or an advisory speed limit (a yellow sign)? It makes a difference in how they should be marked on the map.

A useful technique I've found for mapping apartment complexes and other groups of related buildings is to draw an area around the entire complex, tag it with the appropriate land use (such as "Residential Area"), and put the name on that. It saves cluttering up the map with dozens of identically-named buildings.

It looks like you did what's called a "node drag" here, where you accidentally grabbed part of an object and pulled it across the map. I've fixed it, but it's something to watch out for when you're editing.

Welcome to OSM!

A quick tip for getting good-looking buildings: you can trace the approximate outline, then hit "S" to square up the corners. It sure beats trying to do it by hand.

Thanks for your additions.

Spiral roads like you drew in the southern parking lot here are far from the best way to do things. Routing software tends to be rather literal-minded, and will give people directions to drive around in circles. Instead, you should draw parking aisles as a series of lines or boxes, and make sure that roads are connected (there's a grey dot) wherever they cross.

Thanks for the updates.

A quick tip: this sort of short access road is usually better tagged as a "Driveway" or "Service road", rather than as a "Minor/Unclassified" or "Residential" road.

I'm not sure what you were trying to do here, but you re-named a section of a street as "Chelan Public Utility District".

I've undone the change, but please be more careful in the future.

Thanks for the help improving the mapping of rural areas.

In the future, when you save your changes, could you include a descriptive comment? For example, this could reasonably be described as "Improve road alignment".
