Hello and welcome to OpenStreetMap :)

thank you for contributing to this geographical database. It is much appreciated.

As a word of welcome I'd like to offer some links to the wiki where a couple of guidelines are laid out to help all of us to build a better database together:

This being your first edit it's totally fine not knowing any of the guidelines. One of them saying "be bold" is being followed here.

Still: With this first edit you alerted quite a few people doing quality assurance in their neighbourhood because you changed things in the western USA, Newfoundland and somewhere in southern China which makes this changeset (CS) span most of the world. In the future please try and stay focused with each edit. It's ok to map the world, just safe your work before moving county. Details in the wiki:

There are always questions when working on the database and that's where the wiki (first link is already above, simply browse) AND the community come in. We're always around to help each other out. You can find us in many places online:

And finally, here are some of the basic guidelines

Anyways: happy mapping :)
