Hi, your changeset comment suggests that this need an amenity=cafe tag?

Hi, just wonder why you have removed fhrs:id tags from these places. It a very useful tag.
Cheers Phil

Hi, welcome to OSM.
The name tag should only be used when it is an actual name, It should not be used for a description which in this case can be derived from the tags.
Cheers Phil

Hi, this looks a little odd. Tourism=attraction is a very odd way to describe a Training Centre.

Cheers Phil

Thank you, I will update the library to a building with the museum inside.
Looks interesting so will pay it a visit.

Cheers Phil

Hi, the tag GB:nsl_restricted seems very odd and contradictory. 30/40/50 mph is not National Speed Limit. Is this tag documented or dicussed anywhere?
Cheers Phil

Hi, this edit covers a very large area and at least 3 countries. Please can you confirm that you have visited all of these places and in future it is helpful to local mappers if you can keep such changes to a sensible area. In the case of road surfaces that would be at most a town or village.
Cheers Phil

Hi, you have added a node in the same place as the library. Is this correct? Is the library elsewhere? Have you visited to confirm the location?
Cheers Phil

Hi, OSM doesn't have an Overlay. What are you fixing?

Hi, welcome to OSM. I think this edit has gone a little wrong as a field is a very improbable place to find a shop.
Please remember that OSM is a geographical database used by many people and applications and we only map what exists in the real world.
I am reverting this edit.

No response so reverting

Hi, welcome to OSM. Is there really a waterfall here?
Cheers Phil

Hi, this looks like a very odd route. What is the source please?

Hi, this edit seems to have gone a little wrong. I am a little curious as to why you have replaced these mini roundabouts with actual roundabouts? Imagery confirms they were mapped correctly.

Hi, are you sure about this? Have you been there?
I suspect the the local mapper who added this got it right and as it is at the end of a quiet residential road it a oneway would be unnecessary. Also if it was oneway it would likely be clockwise?
Cheers Phil

Hi, welcome to OSM.
I am not sure this is correct. If the church is derelict it is unlikely to still be a place of worship. Maybe building=church and historic=ruins. The name tag should be an actual name rather than a description, if it doesn't have a name the tag should be omitted.

Cheers Phil

Hi, this is a bit confusing. Is it a Premier Inn as in the name, or Travelodge as in the operator tag?

Cheers Phil

Hi. I have just spotted these edits and realise that the name isn't your doing but it would be good if you could correct the name to "Bechan Brook" and add name:cy=" Nant Bechan".

Cheers Phil

I can add some local knowledge here, this is a track leading to a what looks like a derelict farm, it is not a bridleway although I do not know its legal status.
The road labelled Mountain Track, some name tag abuse, is certainly not a bridleway. It is a track and based on experience the access=no tag is incorrect. It is at least motor_vehicle=private. In this area people have traditionally roamed the mountains pretty freely.
There are clear problems here picked up by the QA tool, but just making the problem disappear without understanding it does not help and makes problems harder to find.
