Hi, are there gates, fence or signs at the point where you enter the private property?

Hi, please don't extend farm areas to the roadway centreline

Hi, you have defined a private property here with the tag landuse=forest. This tag is generally used to define the boundaries of forestry activity. The area is already tagged as being a wooded area.
As the boundary does not appear to be a forestry area or forestry coop, I expect you instead want to show that the track crosses through private property.
This is normally done by splitting the track at each end of the area that passes through private property and adding the tag access=private or other access tag as suits. If there are gates or fences or signs defining the private property you can also add those.

Wineries and other businesses are not added to administration boundaries.

Ok, I’ll shift the doctors to a separate node. I’ll leave it for you to put in best spot.

That's fine.
The building your business is in is tagged
amenity=doctors + building=yes + healthcare=doctor
Is that correct or should the doctors part be shifted to a separate node within part of the building?

Hi, I think this named road should be a track as it drives along the beach. If this is to be named , the other small sections at the southern end should also be named to where it joins the previously named Cape Palmerstone Road section.

no response...changed it

no response...fixed node and unglued two buildings.

Reading the wiki, you can use a type=building relation…

Hi
Dornoch Towers appears on osmi page as an orange dot…

I am not familiar with mapping complex buildings but expect you don’t need a multipolygon for this building and as mapped it is an invalid mp in osm rules for mp (outer ways of a mp cannot be shared).
I expect the solution is to map the perimeter as a building with all tags and then map the building parts as you have already done and delete the mp.

Maybe office=it would be more suitable for your business
office=it

Hi, shop=outpost seems an odd choice to me for an it company. Is this correct?

Hi, I think you accidentally shifted an address node near the bottom of this display - #30A Unwin Road

Hi, why have you deleted the religion = christian tag from the Mormon church.
Mormons consider themselves christian and the tag should remain. If you disagree with the icon used you will need to take that up with the map rendering software instead.

Excuse my ignorance - what is IG?

No response, removed roadway apartment

Reshaped using faint lines that appear to be a fence and name also renders at some zoom levels

As the Geofabrik osm inspector sees it

Outer ways of multipolygons cannot share the same boundary….just draw the courts as three simple rectangles instead and delete the unnecessary multipolygon.
You could draw another polygon around the boundary of the tennis club if you want to name the whole club area.
