craft=carpet_cleaner is not really correct either so I have changed it to craft=rug_cleaner

I consider the office or shop tags to be the primary tag. I use the craft tag to specify if the business also has skilled craft trades available, so it is a separate tag the way I use it, but I may be incorrect in using it as I do.

For you business craft=cleaning now seems wrong after looking at the wiki description.
I think craft=carpet_cleaner is a better tag
I would also add office=company to render your company name on the map as the craft tag does not render it.

I added this business with correct tags.

Are you still fixing these?

Hi, the opening hours format is not correct, case needs correcting too.
opening%20hours=*?uselang=en-GB

natural area like wood should not be connected to the roadway centrelines.

Hi, You appear to forgoten to add the outer polygon to the mp.

I returned the turning circle to the correct spot using DCS NSW imagery

Hi, I reverted this changeset as it only dragged nodes
https://overpass-api.de/achavi/?changeset=183299949
All fixed now.
Also...
Can you try to be more expressive with your changeset comments and write briefly what you have done in the changeset

That's what I would do too.
If each part differed from each other and you wanted to add separate heights or levels, etc then you could draw a separate building:part within the main building polygon for each one and add differing tags.

If it is a roof overhang, the building boundary should be on the outer boundary of the building:part, as building:part is always within the building footprint. Or, shift the building:part under the edge of the building and join the nodes.
As there are two main buildings there would need to be a building:part for each, joining where the buildings meet.
From what you have said this is what it is, so you just need to make the two main buildings a bit bigger to include the roof building:part/s and make two building:part s
It's not clear to me from imagery.

Otherwise, if it was just a separate roof added to the edge of the building then it would be tagged building=roof instead and would not be within the main building footprint.

If this is unclear, I can do it.

Having downloaded a vast area of small polygons tagged with wood or forest I can see this has been done systematically by many mappers so I'll leave to others to manage.

Hi, are these errors from your mapping? or are you trying to fix the mess?

I would think all the much too small wooded polygons need to be deleted and then be remapped using Josm and encompassing whole wooded areas in multipolygons with inners.

Hi, this mp is in error in a few respects.

This is fixed now

I have removed the invalid mp and changed to one simple polygon.

Chemist Warehouse is the mp
