Hi there, it looks like you're downgrading the status of numerous cities in the United States. In OpenStreetMap, changes of this magnitude should be discussed with the community first. Some of us are discussing these changes in the OpenStreetMap US Slack (https://openstreetmap.us/get-involved/slack/), but the community forum at https://community.openstreetmap.org is another great choice for these discussions. I'll also direct others here so you can reply in this thread any anyone concerned can see. 

I'll note that most of your changes are against the community consensus and will probably be reverted. To start with, could you share what information you used when deciding to downgrade Scottsdale to place=town?

Thanks, and welcome to OSM! We'd love to see you in those community discussions!
