Hello,

I see you requested a review.

Nice to add this.  Cool to have a LUG on the map!

I am not sure whether "amenity=community_centre" and "community_centre=club_home" are appropriate.

I would tend to only have club=linux on the node.  But though it will be searchable, there will be no icon on the main map.

Another issue is the location.  If you put the address as 121 we’ll have a duplicate address with this one which you moved a few years ago: https://www.openstreetmap.org/node/2622408355 ← and indeed the location of that node matches UrbIS data.

Are you sure Caldarium is in the correct building?  Shouldn’t it there be near the node with housenumber 121?  If that is the right building, I suggest removing the address entirely on Caldarium.
