Hello and welcome to OpenStreetMap,

thank you very much for contributing to this database.

As this database is used by millions of people every day there are some guidelines which the community decided upon and which should be observed. As a new contributor it's near impossible to know them all so I'd like to offer some comment and some links so your future edits will be even better:

- please keep your edits local. Save your changes before moving town. Here you touched Norway, Sveden, Germany and Japan and alerted quite some people to your work ;)

- please only add names when things are verifiably named. Do not add descriptive names like "Half Pipe". Check the wiki or ask the community if you don't know how to tag something.

- in case of questions that you can't answer using the wiki please contact the community. There are many ways:
