Also, instead of re-tagging the 136-138 Rowe Street address add a new node for the studio at 33 West Parade for your studio.

Hi, welcome to osm.
I had to revert both your edits due to dragged nodes and addresses and also the retagging of landuse=retail to a building=retail as the area is not one building.
Please re-add VQArtStudio and zoom in much closer so you don't accidentally select and move other nodes.

I attempted to fix this area a bit but don't know extent of church.

Hi, you have placed two defibrillators here, one on top of the other.
Are there two here or should I delete one?

You need to add a new node at the physical location where your business is based instead of added the details to the suburb point. The above link with help.

Hi, this is not the correct way to add your business to osm and I have reverted it.

Hi, these appear to be fictitious.
Can a person familiar with the area confirm this mapping.

I have reverted this suspected vandalism.

I think TheSwavu might have fixed it

I suggest a polygon drawn around perimeter for the mall.
Multipolygons are not the same as multiple polygons joined together and have to be formed in a valid way as in the documentation.
You could also map it all using the building:part method which would be a polygon around the perimeter and a polygon for each part but the standard layer only renders the outside polygon.

Hi, the shops multipolygon is invalid because outers cannot share sides.

Just draw simple polygons instead.

iD is not really suitable for editing such large multipolygons.

Hi, multipolygons cannot share sides. I have fixed by making simple polygons.

no response, reverted business not mapped to a specific building location. Appears to be online only contact.

Thanks for letting us know. Josm will reward your efforts many times over.

I decided not to revert these areas because I don't understand the full extent of the changes and why they were made
