Easily done....I have fixed these.

At the bottom right of your edit area you will see you have dragged a couple of nodes. I have fixed these. It is a problem that is easily done while using the iD editor that you need to be careful with.

Hi
on St Bernard's College grounds you have added building=school. This tag is used for the individual school building footprints instead. amenity=school is sufficient for the boundary of school.

no response, reverted what appears to be a mistaken edit.

The building=house tag is used to outline the building footprint or roof area instead of the plot of land.

Hi
I think you may have created a few self intersections in the Forest Lake Shopping Centre

Let me know if you are having trouble fixing them.

Hi
This building appeared to be correctly mapped. Why have you deleted it?

Your welcome...it takes the whole community to maintain the osm

I have moved the variety shop to the new location and vacated from Rowe Street. Any others like this, let me know.
The map rendering should update in a day or two.

Ok, I have a look tomorrow.

Hi
the address you have added to the business is not correct.
50 Blaxland Road, Ryde is in a not near here. Did you instead mean to map a building footprint at 50 Blaxland Road, Ryde and add this business details there? Please delete the incorrect details added here and add them to 50 Blaxland Road, Ryde.

Building tag is for the building outline only. If you wish to mark the bounds of the property from satellite imagery, it is best done by mapping the fence lines.

Hi, the building tag is for outlining individual buildings instead of the land plot

I split the roundabout instead of adding a duplicate segment and this fixed the route relations through the area too.

I added a segment to the roundabout on Winstanley Street to fix retail multipolygon that uses road segments for the landuse=retail boundary at Westfield Carindale, se Qld. Too much work to redraw without using roadway infrastructure.

At version #17 for the landuse boundary so has probably been the way for for a long time and use to be a common or even preferred way to map landuse but it considered not to be the preferred method now by my reading of mapper discussions.

It is normally preferred that you don’t use the highway nodes to form boundaries for landuse. Leave them solely as road infrastucture. The land use does not extend to the roadway centrelines. Using roadway centreline nodes may be convenient and may the map look pretty but is not the preferred way to map.
There was an osmi error with this one tonight…

I have reverted the changes to restore the power line track

The track is there for the power line maintenance crews to access the actual power line which is the straight line. The track is also used by hikers.

Hi
You appear to have turned this footway into a power line.
