Welcome! Thank you for adding the business to the map. I would recommend to add a link to the YouTube channel instead of the playlist to the contact:youtube tag, but the rest of your edit looks fine. If you have any questions feel free to ask.

Welcome! Thank you for your first edits. I noticed that you had Capslock activated while adding the address of the church. Could you please fix that? You also added a duplicate of a park that was already mapped as an area. If you have any questions feel free to ask.

Welcome! Thank you for your first edits. They look very good already! If you have any questions feel free to ask.

Hallo Endlesskeks, willkommen bei OSM hier in der Region! Wenn du irgendwelche Fragen hast, kannst du sie mir gerne stellen.
Ich habe gesehen, dass du ein Objekt 'leisure=Säule' genannt hast. Bitte erfinde keine eigenen Attribute, sondern versuche, mit dem, was OSM hergibt, auszukommen. Ansonsten sehen deine Änderungen schon ganz gut aus!
