Hi Martin,

I didn’t have time to review your work, but just wanted to add: don’t
despair if you complete some tiles and they aren’t promptly validated! HOT
has grown a lot in the past year or so and we have a lot more mappers than
validators as a result. So sometimes it can take a little time to get a
response. Posting to the listserv like you did is a great way to call
attention to tiles that need a second look. Welcome to OSM and keep on
