Dear 호버트,

OpenStreetMap is a collaborative project where other mappers look at our contributions and check them. This is good, because if many eyes look at something, errors can be avoided!

It is important that you use a good comment on your changesets, so that others can understand the scope and reason of your edit. Please see osm.wiki/Good_changeset_comments for more details.

Thank you
Frederik Ramm
