Hi. For errors regarding Nomonatium, I  do still see Fort Wayne. I could have easily made a mistake of some kind with this, but being relatively new to OSM, I cant tell.

As for neighborhoods being vague, an official cite made by an official city development dept a few years ago (https://gis.acimap.us/portal/apps/sites/#/data-fort-wayne/pages/view-the-data) lists West Central, East Central, Spy Run, and Northside as neighborhoods, as well as gives gis data for them. I'm not sure how I didn't add the citation correctly, but will try to do that. The area edit I made for Waynedale should be removed though. I realize it's too vague to be accurate
