You've changed part of the Missoula border (way/34746177) into an improbable-looking shape. Was this intentional?

Please don't add nonsense to the map, even if you find the local traffic engineers' obsession with roundabouts annoying.

Is this an import from somewhere? Most if not all of the volcanoes you've added here duplicate existing ones.

You can mark a trail as "unofficial" by adding the "informal=yes" tag to it. It's not one of the tags that the iD editor provides by default, so you'll need to add it manually:

1. Select the trail in the editor
2. In the panel on the left, scroll down to the "all tags" header and click on it.
3. Click the plus sign
4. Add "informal" to the left-hand box and "yes" to the right-hand one.

(The "informal" tag is also useful for other things like unofficial parking areas.)

Where are you importing these buildings from?

You've added a service road with the type "Kallispell Access Lane". Was this supposed to be a name?

The usual way to tag this sort of business is as a "Cafe" with a cuisine of "coffee shop".

Welcome to OSM, and thanks for adding businesses to the map!

Something to keep in mind when you're editing: when you add a tag to something, the editing software sometimes automatically applies additional related tags. For example, when you added the "Storage rental" tag to Skyview Storage, the "building" tag also got added, making it look like the entire area is a single building. You can remove these extra tags by clicking on the "trash can" icon next to them.

Thanks for your additions.

Elevations in OpenStreetMap are specified in meters. By giving High Camp an elevation of "6123", you're making it one of the highest points in North America. I've fixed it, but it's one of those "gotchas" need to keep in mind when adding things.

"isolated_dwelling" is almost never the correct tag for places in the United States. If you think you've found one while cleaning up GNIS, it's probably either a former town, a former railway stop, or you need to look around to find the rest of the hamlet.

Please don't glue unrelated objects to roads like you did with Town Square Park here. It makes it difficult to modify the roads later, such as when splitting one to add lane information or speed-limit changes.

If it's got a well-defined flow direction, then "intermittent stream" seems reasonable; if it's just a low spot that collects water, then I don't know how I'd tag it.

A cycleway that's also an intermittent stream? Is this a tagging mistake on your part, or a design mistake on someone else's? way/634162906

You added two houses both numbered "4612 West Elderberry Avenue". Was that a mistake?

Cheney? I think your aim's a bit off.

Thanks for the addition.

It's better to put address points on the actual building than on the street: this way, more sophisticated routers can do things like say "your destination is on the right", or find a walking route that involves fewer street crossings.

It's easy to do: simply start editing, right-click on the address point, and select "Extract" (the third item from the top of the menu). Then move the point to the correct location and click to set it down.

The Wikidata item you linked to is about the tribe, not the reservation.

When was that designated WA-907? The state Department of Transportation doesn't seem to know anything about it.

Why did you delete the Mountain Standard Time zone?

The map isn't updated at all zoom levels at the same time. The higher zoom levels usually sync up in an hour or two, a couple days at most, while the lower zoom levels can take longer (when I was mapping some farmland around Spokane, it took nearly three months for it to show up at the "all of Eastern Washington" zoom level).
