Hello,
Is this a business? If so you should tag it on the building way instead of a node. Also, names and addresses should be capitalised

Hello,
Unfortunately there is still a call to action (to contact). It's best to just leave the first sentence in the description and use the website/phone tags for contact information.

Hello,
Welcome to OSM. This building isn't called "Home". If you want to mark this as your home you can use a 3rd party app for that.

Hello,
Thank you for improving the map. Everything is correct except for the description; please don't add lesson pricing to OSM as it could be seen as an advertisement which is prohibited.

Hello there,
You do not need to add these tags since by default everyone can use this road. By 'do not need to' I mean please do not do this.

Hello,
You tagged surface=no instead of sidewalk=no. I'll fix it

Hello,
The cycle lane suspension is temporary, we do not map temporary restrictions in OSM.

Besides, I could think of a number of ways to turn here on a moped or bicycle without creating danger.

The point I'm trying to make is that these kinds of unsigned/implied restrictions are dependent on the vehicle you're driving - lorries can't u-turn at most intersections, doesn't mean we should add restrictions for them. In the UK, common practice is to only add restrictions if there are signs prohibiting a turn or single solid lines needing to be crossed, otherwise the Highway Code doesn't prohibit turns.

Спасибо, буду иметь ввиду

Hello,
Thank you for improving OSM. "access=yes" is redundant as it is implied for most highways. Please don't add it unless it's unclear what the access restrictions are (such as for a gate or rising bollards).

Unless there are signs or solid lines this isn't illegal. Maybe in a car it wouldn't be safe but one could easily u-turn here on a pushbike or scooter. Please don't add these kinds of unsigned restrictions.

Are these manoeuvres illegal?

I urge you to read these wiki articles. OSM doesn't follow council statements, rather common practice and what's on the ground. In places where language speakers are at least roughly 50/50 (e.g. Na h-Eileanan an Iar, Belgium, Switzerland) we have two or more values in the name tag. The only region where Scots Gaelic is the majority is Na h-Eileanan an Iar, where you can see the name is already in Gaelic. If you want to be able to see the Gaelic name in place of the English name you are welcome to create a renderer that prefers name:gd.

To save yourself the work, next time I would advise checking the wiki (osm.wiki/) or discussing your changesets on the OSM forum (https://community.openstreetmap.org/); especially for large and/or controversial changes.

I'm afraid probably all of this user's name-related changesets should be reversed. They have either added two names to city name tags or added the Scots Gaelic name to alt_name, neither of which is correct.

"Obar Dheathain" was added as the alt_name for Aberdeen, even though there are many more Scots speakers than Gaelic speakers in the region. Has there been any official legislation change to city names? Besides, this information is already stored in the name:gd tag

"Obar Dheathain" was added as the alt_name for Aberdeen, even though there are many more Scots speakers than Gaelic speakers in the region. Has there been any official legislation change to city names?

This large number of undiscussed changes to name tags is worrying. Surely the precedent is naming cities in the native language in areas where it predominates (e.g. Steòrnabhagh)? Hopefully this mapping isn't motivated by personal beliefs.
