The operator name should not be in parentheses - it should just be
operator=Frisco Police Department
instead.

Looks good, thanks for your contribution. There was a small segment of Great Oak Circle that still had the old name, so I fixed that :)

Is it "Pineview" or "pineveiw"? :)
Please try to write a more descriptive changeset comment that briefly summarizes what you are doing, as well.

This road, the lake name, and the trail surrounding it don't appear to be on aerial imagery. What is your source for this edit?

Welcome to OSM! Looking at bing streetside imagery, these look to be bicycle_parking=wave, not bicycle_parking=rack. The wiki has good example pictures:
bicycle_parking=*

Otherwise, this edit looks good to me.

Welome to OSM! For trails which are closed to the public, please don't delete them - someone will most likely come back and readd them. Instead, you can use access tagging to clearly indicate that they are not open to the public. Wiki article for reference and further explanation: osm.wiki/Why_can%27t_I_delete_this_trail%3F

Happy to chat further if you have any other questions!

Good catch! I also renamed the remaining section of Sabine Street to the new name that was a bit north of the main part, based on bing streetside.

reverted - you changed the name of a nearby service road. Please take a look at the built-in tutorial.

No worries, happy to help. If you plan to edit more on mobile, I really recommend using a dedicated app instead. (Go Map!!, Every Door, StreetComplete are great options to start with) The browser editor is pretty awful to use on your phone, as I'm sure you noticed!

Welcome to OSM! I have reviewed your edits - it looks like you might have drawn new highway ways on top of the existing ones and named them. Instead, you should use the existing ways (and split them if necessary.) I have cleaned that up, but can you please confirm that the names are correct. Let me know if you have any questions.

Welcome to OSM! Thanks for your contribution. Not every feature needs a name, and in general you should not put descriptive names (like "Single Family Home"). I have fixed that for you. Happy mapping!

Google streetview (and almost everything else in google maps, really) is not an acceptable source for OSM contributions because the license is incompatible.

you dragged some of the service roads into the building, which I have fixed. Also, I fixed some of the tags on the new grocery store, which you can review here:
changeset/161592625

Thanks for your edits, and excited to see this place finally open!

Welcome to OSM! This was already mapped as a playground - I have removed the duplicate you added.

I went ahead and made the edit, you can review it here:
changeset/161499321

Welcome to OSM! I have taken a look at your edits - traffic_sign=stop should only go where the traffic sign is, not on the highway. Otherwise, these edits look good to me.

Looks good! Thanks for your contribution.

Welcome to OSM! In general, name=* should not be used for descriptive names like "Drainage Easement" - it's totally fine for you to add things to the map without a name.

I have fixed this for you, you can see my edit here:
changeset/161444247

Welcome to OSM! highway=cycleway is probably not appropriate for single track paths, I would personally use highway=track - otherwise these changes look good.

The wiki has some documentation on tagging for mountain biking, in general - it's a great place to start.

I have reviewed your edits and it looks good to me. Note that surface=concrete:plates is quite a rare thing compared to surface=concrete, see the discussion here:
