Thank you for your work on this!

Thanks for adding all these sidewalks -- they look good! In the future, please use slightly more descriptive changeset comments; something like "Added sidewalks and traffic humps in Stop & Shop parking lot and surrounding streets" would have been perfect.

Thanks again for your work!

There's no particular need to roll it back -- just be more careful in future. All good! Thanks for your work in any case.

Er, this doesn't seem to have to do with the linked MapRoulette challenge, and it has a very large bounding box. Could you explain more about what you were intending with it?

I think you accidentally moved osm.org/node/1483044717 in this changeset. I've put it back now, in osm.org/changeset/161802395

Please break future changesets like this into smaller pieces, rather than covering such a large area. Thanks!

Thanks for fixing (with osm.org/changeset/161564474 ) the unintentional changes in the US that got made in this changeset.

Thanks for adding these two buildings shaped like objects, but please try and avoiding adding them so far away in the same changeset!
