Hi there and welcome to OSM :) Thank you for your contributions

You tagged these as amenity=school (School Grounds), which is meant for tagging entire schools overall. Perhaps School Building or just the name tag would be better?

amenity=school

Happy mapping,

Hi UKSAR936, welcome to OSM and thank you for your contribution!

You added "natural=water" and removed "place=island" from the Great Britain relation, resulting in Great Britain being "flooded" with water rendering (which you probably noticed).
Accidents do happen, we all make them, but please take care in future.

Another user has now rectified the relation (changeset/142930228)

Thank you, and happy mapping :)

Hi there - the brand Post Office in Welsh is Swyddfa'r Post with 'r

Then you should always cite the 'source' upon saving (eg. "survey" if you've seen it for yourself) and replace what you've removed with the new data.

Hi there! Did you mean to delete all of these elements (particularly the landcover)?

Please don't delete data unless you know or believe it is incorrect

Thank you!

Great, thank you! I'll place a note

Hi there!

I feel like this could be 'Pont Felindre' and not the mutated form ('Bont') since there is nothing that would mutate the P - could you please check?

Diolch
