Hello, thank you for your contribution.

Please considere these things:

1. edit a small area (within a city or small region) and then upload your changes before moving to another area (see https://wiki.openstreetmap.org/wiki/Changeset#Geographical_size_of_changesets)

2. add a comment describing what you changed (see https://wiki.openstreetmap.org/wiki/Changeset#Tags_on_changesets)

3. avoid descriptive names to features (see https://wiki.openstreetmap.org/wiki/Names#Names_are_not_for_descriptions)

If you have any questions, feel free to contact me or have a look at the wiki and the forum.

Have a nice day!
