Ok, I think I figured it out from the #OSM online editor. But if someone more experienced with OSM wants to review this addition, here it is: https://www.openstreetmap.org/changeset/178278251#map=15/59.76072/17.60999

On @CoMaps, I see buoys marked on a lake. They are categorized as "lateral buoy" when I edit them. Today I went skating on said lake (it's all frozen, wonderful!) and went by a lateral buoy that's not on #OpenStreetMap yet. Trying to add it from CoMaps, I couldn't find the "lateral buoy" category in the long list of categories under "add a place to OSM". And my hands got cold. So I simply saved the coordinates and decided to add it later from the OSM website. Now trying to do that, but the website doesn't even show the other buoys that CoMaps shows me... so I am confused. If any #OSM contributor reads this and knows how to add such item to the map, I'd be happy to learn.
