Hi,
If the Arches Leisure Centre has closed then you can edit the "leisure" tag to "disused:leisure". That'll make it clear that it's not currently a leisure centre at the moment (rather than one with "closed" in the name).
You'll need to use an editor at the osm.org website to do that though - maps.me won't be able to.

Here you've changed the "name" key to be in Tigrinya (which makes sense if that's the majority local language) but you've also removed the "name:ti" key. That may not have been deliberate - it can be useful where there are lots of names for a place in lots of different languages to have both "name" and "name:ti" (even if they're the same). It doesn't make sense everywhere (where there are fewer names for example).

Oops, relation/2788397 is a duplicate of the complete Ebor Way relation relation/370663 . This one was created by a new mapper - it's always worth checking for related errors if you spot a tagging issue, just "fixing the tags" rarely actually fixes the error.

Hello,
OpenStreetMap is a map of the real world. Please don't add fictional data to it.

For info, I've reverted the other rubbish that this user had added.

Hello,
Please don't add test data to the live OpenStreetMap Server. If you want a test server, perhaps http://api06.dev.openstreetmap.org/ would work for you?

Hello and welcome to OpenStreetMap!
Here you seem to have drawn a box around Sketty as a residential road way/437063079 . I'm sure that wasn't there the last time I drove through, so I've deleted it.
OpenStreetMap is supposed to be a map of the real world - if you want to draw things that don't exist you'll need to find somewhere else (and depending on what you're trying to do, we may be able to suggest somewhere).
Best Regards,
Andy

Excellent! Thanks.

If you're copying the names, then you're copying, not referencing.
Of course, if you have local knowledge of then names (maybe you're a long-time Esperanto-speaking resident of Antarctica!) or if you have an appropriately licensed source (which is surely going to exist) then you're fine.

Hello,
Under what licence is the source that you have used here made available?
Best Regards,
Andy Townsend

Hello,
Please note that (perhaps surprisingly) wikipedia isn't licence-compatible with OSM. You can't copy from wikipedia to OSM. You can, of course, get to exactly the same information via a wikipedia or wikidata link.
Best Regards,
Andy Townsend

Hello,
Can you explain under what licence you obtained way/436774890 ? The source document is clearly marked as Crown Copyright. Did you get an explicit exemption from them?
Best Regards,
Andy Townsend

Hello,
Are you sure that all of these individual places are really named after the same person, or are you just guessing?
Please note that mechanical edits need to follow the policy outlined in osm.wiki/Automated_Edits_code_of_conduct .

Hi,
node/4344893489 seems to be one of three adjacent campsites. Are they all perhaps really the same one?
Cheers,
Andy

It's already been changed back, but I'm pretty sure The Filling Station was still called that when I walked past it a couple of months ago.

Just checking - should way/38572070/history be both an abandoned railway and an admin boundary? If it's the west edge of a cutting I'd guess that it's not actually a (former) railway, and if it (the NR) lies wholly in the county, wouldn't that make the admin boundary the East rather than the West side of the cutting?

Just for info, I reverted the node drags in the previous changeset here but left way/434932382 as you left it.
I think it's all OK now, but it would do no harm for you to check :)

Hi Stan W,
Somehow a couple of roads got joined together (East Street and Logan Street). I've unjoined them, and changed the BOAT back (to Mike's version). Hope this is all OK...
Cheers,
Andy

@alexkemp , Please tone the comments down a bit. Saying things like "Diamonds to a pig", "you punch me, I punch you back, often & hard" and "I trust my personal experience better than someone else's intellectual considerations" don't help to communicate your message; in fact they have the opposite effect.
Consensus is valued in OSM - if you've got three people saying "you're doing it wrong" it's usually an indication that at the very least you might want to step back and reconsider, or perhaps try and engage a wider community (perhaps via the talk-gb list).
Cheers,
Andy (wearing a DWG hat)

In addition to footway=sidewalk on way/4072398 I'd also suggest sidewalk=separate on way/136720321 .
(I know that this all dates from changeset/24421774 , but that mapper appears to be long gone)
Cheers,
Andy
