OK, many thanks.

You deleted the hairdresser, then recreated it as well as deleted the pub. In your changeset comment you wrote that you only deleted the hairdresser. What is correct? Did the pub close? Did the hairdresser close down? Did a new one replace it?

Great. Thanks for your contribution.

As this edit creates a house number duplication (the number 2 is already on the map) and as a node can't be a building, I'm going to delete this node but to associate the added postcode with the current house number.

Do you mind if I remove the fence you added around a Marchmont urban block? The reason is that it appears now that this block is segregated and requires an access. For info, we added some external fences and gardens in order to show where the gates are (see here: osm.org/#map=19/55.93516/-3.22923). We didn't go on with that (at least not at the moment) because it's too time consuming.

Thanks for your answer. drnoble already improved it.

No problem. Thanks for that.

Named Murrayfield Stadium (relation) changed the rendering of the stadium. Now it appears as a normal building (we can't see anymore the pitch -- that's why the name was attached to the outer way and not to the relation).
Do you mind if I update the relation to remove the name for now and to add a note instead to indicate the name? Thanks

Is there any particular reason to duplicate addresses here?

I merged the two buildings and added Drill Hall as an alternative name for the Out of the Blue Drill Hall building (so people can find the place by searching both names). Change as well the opening hours of the cafe and the source tag to fit the OSM specifications.
Hope is ok for you.

Hi there, you said that technically separate but it's the same building here and not two buildings. The Drill Hall Arts Café is inside the building. So I'll revert your edit here if you agree.

no problem (thanks for your comment)
