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!

Welcome! Thank you for your first edits. They look very good already! To display the gas station on the map you also have to mark it as such with a preset in the editor. If you have any questions feel free to ask.

Welcome! Thank you for your first edits. They look good already! It seems like you added some duplicates, so please check if it is already there before you map something. If you have any questions feel free to ask.

Welcome! Thank you for your first edits. They mostly look good already! Please add a descriptive tag to this node. In its state now it is pretty much useless. If you have any questions feel free to ask.

Welcome! Thank you for your first edits. They look good already! Unfortunately, you used the wrong preset for the church. Look for 'Christian Church' instead of 'Religious Area'. If you have any questions feel free to ask.

Welcome to OSM! The bridge was already mapped, so unfortunately I had to delete your node again. If you have any questions feel free to ask!

Sorry, but adding your business to a street is not the way we do on OSM. Please add it as a new node next to the street at the exact location of the office!

Welcome! Thank you for your first edit. If this is a driveway you can also tag it explicitly as such. Living Street is mostly used in urban areas. It is also enough to add access=private, because it automatically implies all other access restrictins. If you have any questions feel free to ask.
