So you're saying that the owners confirmed their newly built development was a field of grass and that the roads had been torn up for footpaths?

Your recent edits are a little concerning - please do not make deliberately incorrect changes to OSM.

If you want to map the parks and footways here for Pokemon Go, please do so accurately.

I can see a lot of real footpaths and other details you can add here.

Hi and welcome to OSM!

Thanks for your recent edits.

Some advice - try to avoid attaching areas like parks to all adjacent roads as it can make editing those roads and park more difficult in the future. A park rarely actual "stops" in the middle of a street where the roadway should typically be marked.

Hi and welcome to OSM.

It appears that you've mapped a park over several residences and a road here, please only add real features to the map.

Hi, I think you mapped this slightly incorrectly - you placed the park area for McMaster Conservation Area so that it just covered the entirety of McMaster University - clearly not a park or conservation area across the whole location.

Hi again!

What are you trying to map here? You've got a lot of duplicated tags all stuck on top of each other, but I'm not sure what this actually is?

Hi! Thanks for your recent additions to the map.

Regarding this edit, there's no reason to add additional land use and leisure tags to this golf course. Even in Pokemon Go, leisure=golf_course is a nesting tag, everything else can just cause a tagging conflict.

Hi, what are you trying to map out here? There's already a park and university mapped at this location.

It's probably one of those "limits on private information" cases:
osm.wiki/Limitations_on_mapping_private_information

Verifiability is important on OSM, if I turned up and started running around in your backyards, you'd probably call the cops.

A lot of your edits seem useful, but it's hard to keep track of what your doing without using a changeset analyser.

Did you mean to set the entirety of Youngstown State as landuse=pub? Funny, but probably not entirely accurate all of the time.

Hi and welcome to OSM!

Thanks for your edits so far, most of them look great!

Unfortunately, in this case this wasn't the correct use for the park tag. Check the wiki for more information:

leisure=park

This is still incorrect. A park is not a sidewalk. Please do the tutorial and check the OSM wiki before making further edits - what you are doing here is not useful and helps no one.

This isn't how you add sidewalks and footpaths. Please stop and read the message I sent you.

Hey! That's not how you add sidewalks! You're changing roads into footways here.

changed to a path*** not a park. Too used to correcting fake Pokemon Go parks.

Please stop vandalising OSM. This is not a park.

Why are you changing residential areas to parks?

Hi and welcome to OSM - the feature you've added here is already on the map. Where you trying to add additional details? Let me know if I can help :)

Hi and welcome to OSM!

What kind of garden is Sophie's Garden? Is it private?
