no response, have tried to fix myself remotely

I have adjusted the tags and removed some promotion text.

Hi, you have changed what was mapped as an intermittent waterway to a path here. I think it looks like a dry creek bed to me from imagery.

Thanks for fixing - looks good now.

Osmi displays the error here

Hi
Multipolygon members with outer roles cannot share sides if they are to be a valid mp. I suggest dropping the multipolygon relation and map as a simple poygon around the whole area or if you prefer 3 simple polygons to cover the area.

Hi
is Jack's House the correct name of this building or is personal information?

Hi, osmi has detected a few problems with this area.
https://tools.geofabrik.de/osmi/?view=areas&lon=149.01348&lat=-35.29797&zoom=16
The postcode boundary appears to be especially affected
relation/11661751#map=13/-35.30938/149.01581
I expect it might be easiest to revert until errors are resolved.

It is best to leave owners names off the houses you are mapping.

This level of personal detail is not appropriate and is deleted.

Hi, You have deleted the tags that described a power pole here. Can you review this as a power pole appears in imagery.

Hi, you seem to have dragged some nodes here. Let me know if you are unable to fix.

I reverted this as the suburbs are already mapped by area boundaries.

This road is closed and a new underpass to be built.

I re-added the water bubbler

Hi Jamie
I have redraw the apartments so that the individual buildings are mapped as is conventional in osm. Because there are two apartment buildings at #29, I put a new node near the letter boxes for the address instead of duplicating the address on the apartment buildings. I deleted the state, postcode and suburb as these are mapped as areas in osm in our country and they are not required.

Is this a permanent change to not allow vehicle traffic across the rail crossing on Webster Street?

You appear to have added the bubbler to a boundary instead of a new node and shifted a bench and a flagpole incorrectly.

I have reverted your changeset.

Hi, both your business additions to the osm have been reverted and the map restored. The method you have used to add the businesses is considered vandalism.
You should instead add a node to the location your business operates from and add the business tags to that.
