1) "even though you are not from the same country" should not be a problem as osm is an international project.

2) Contention here is that what's on the receit (paper slip really not a real receit) is automatically name=NN in osm-lingo. Well there should be a thought process between reading the paper slip and transfering the information to the relevant and correct osm-tag. When it's
a) one legal entety,
b) name is the same all over the country from north to south (same as officially registred name),
c) company- and brandname are so thoroughly established

than one can only come to the resonable conclusion that it should be name=Systembolaget.

3) Re searchabillity on osm carto. Should not be a problem: osm.org/search?query=Systembolaget%2C%20Borl%C3%A4nge#map=11/60.4562/15.5045
One should however not visit these shops too often with the intention of making purchase...

This is - or at least should be - very simple. According to Bolagsverket - the swedish central authority and registry for companies - there are only two (2) companies regestred with the name Systembolaget.

1) Systembolaget Aktiebolag (a limited - not even public! - company owned by the swedish state,
2) Systembolaget Dataassistenten (presumably Systembolagets company for their IT business)

Systembolaget is doing business via their branch offices (outlets) thruout Sweden with their brand name "Systembolaget".
Other construcs like Systembolaget NN are a product of ones own fantasy.
Systembolaget - like all big companies - is very keen not to delute their company and brand name by calling one shop (outlet) for Systembolaget NN1 at one place and Systembolaget NN2 at another place.

Vänligen ändra inte namnet på fyren. Den heter inte "Fyr" för det är ett självbeskrivande namn som inte säger mer än vad taggningen redan "säger" och det får inte finnas i osm. Låt det vara "Fårö fyr". Tack!

You inserted two errors by this cs.
1. you inserted duplicate segments in the mp-relation,
2. the grass area was an inner of the surounding scrup-mp-relation. When you inserted the beach-polygon you should have changed the status of the grass-polygon.
Pleas fix this, thanks.

By this cs you destroyed the forest-mp-relation. Would you kindly fix this, thanks.

Well, never mind. Thank you for correcting.

No, the values of the addr:-tags.

Do you really think that adding "changing_table" etc to a zoo's outer boundaries makes sense?

Hello, you must have noticed that nearly all of the buildings you create are not rectangular. You could easily achieve this by simply marking the outline of a building and then press key "Q" on your keyboard. Try it!

Please take your time and read the wiki article about names: osm.wiki/Names

Could you please abstain on putting the name-tag on everything. Those are already marked w network=Styr & Ställ and now also brand=Styr & Ställ. Please read the chapter about named in the osm-wiki.

The address-tags seems to belong to another place in another country.

Hallo, bitte beachte folgendes:
1. Strand nicht als node (Punkt) sondern als Area,
2. Keine selbsbescheibende Namen und hier in Schweden schon gar nicht auf deutsch.
Danke!

I understand. I placed the diving tower inside a closed-way pir.
I take it you are on vaccation. I'll keep an eye open for your edits an will complete them (if you don't mind).

Jäklar! Vilket konstverk! Verkligen gediget arbete! Respekt!

Hej, om du kollar vad Emmaus verksamhet går ut på, kommer du ofrånkomligen till slutsatsen att den bör taggas som shop=charity + second_hand=only. Dvs en välgörenhetsorganisation som främjar sitt syfte genom försäljning av secondhand föremål.

Forget about it. I did complete it based on information from the municipalety (https://kalmar.se/uppleva-och-gora/natur-friluftsliv-och-parker/parker-lek-och-odling/lekplatser/aktivitetsparker-i-kalmar/kalmar-wake-park.html)

Hello, just a node wan't do (sport=water_ski). Please complete w closed way, otherwise there will be varning from the validator of editors. Thank you!

Thanks, this is very sensible, as swedish timetables state "NN station" as halts. This makes it possible to search for the "NN station"-value.

Tagging highway=path+bicycle is rather meaningless as highway=path allready consists of bicycle. Before making changes please read which highways have what values by default: osm.wiki/OSM_tags_for_routing/Access_restrictions#Sweden
