Hi, 'primary road' is intended for major public roads, for a racetrack you should select 'motorsport racetrack' in the map editor.

Hi, is there a reason you have deleted pedestrian crossings and retagged pavements and footpaths as highway=path?

Is this really the housname of this building? Private information such as names should not be added to OpenStreetMap.

Hi, the correct way to change the grass to a kerb would have been to remove landuse=grass and add barrier=kerb. I have updated this in changeset/118485302.

I have moved the former name to a dedicated tag old_name, hope that is ok. I also removed what looks like a tracking id from the web address.

No problem, hopefully at some point in the future all the public footpaths will be tagged with prow_ref to prevent confusion :)

This footpath is shown on the Herts Public Rights of Way Map (https://webmaps.hertfordshire.gov.uk/row/row.htm) - is there any information to the contrary apart from the anonymous note?

Hi, if you want to update some tags about a business please modify the existing node rather than deleting it and retagging a nearby parking tickets machine. Thanks.

And mapped a tennis court and swimming pool with building=yes?

Why have you added golf=rough and landuse=grass over a substation, playing fields and surrounding fields?

And added a golf cartpath on top of an existing service road leading to a substation?

Why have you deleted the golf club car park and added golf=rough and duplicate footways inside it?

Was it intentional to tag this multipolygon with landuse=forest and natural=water?

Ok, thank you for your advice, I only learned how to map in OSM yesterday so any feedback is valuable.
