All public transport station are mapped please don't add duplicates.

Hi
This edit appears to have broken NCN24. Could you take a look at it please.

Is the ref really 'ref'?

And here please.

Could you check this edit for Cotswold Way relation.

Hi
Are these C1000 - C3000 road refs or refer to something else?
Do you have a link to the source?

Hi
Could you please take a look at this school if you've the time. Does the school boundary bisect the buildings & I'm pretty sure the recreation ground doesn't go around the whole site.

Hi
Single objects don't need to be Multi Polygons.

IBM is not a functioning railway station.

I'm a bit confused by your comment as my point was you placed the ref in the name tag.

As minor roads (C,D,E) aren't usually signed it was decided to assign them a separate key to give renderers the choice whether or not to display them.
Plough through this discussion:

I see agricultural as a subset of private.

Hi
The classification of bridleway excludes motor vehicles. access=no excludes all modes.

Hi
Please don't add refs as names or change designated to yes.

Please don't remove area tags from railway=platforms. It messes up the render.

Please don't assume iD is reliable. It's presets are often set to the developer's desires rather than those of OSM contributors.

Hi
All network rail stations exist. Please don't duplicate them.

Hi

Is it a crossing of a bridge?

Hi
Please don't tag incorrectly to suit validation software. iD validation code is poor in many situations. All you have to do is not accept their inaccurate suggestions.

Hi
Do you know the building's purpose now?
