It looks like the street name is in all caps. I doubt that's the case in reality.

Fat fingers... that's what I get for using iD on my phone.

It's not an official policy, but it is courteous to other editors trying to review edits. I can understand that it's irritating to submit a bunch of changesets with a single edit each, especially since Level0 has no good way to do this, but perhaps you could try to split them up by country.

There's no way with the ID 900000000, but you created the next ID right after, 900000342. Congratulations on (sort of) creating the 900 millionth way!

I accidentally put the changeset comment in the source field. Oops.

Sorry, subdivisions. There's a lot more than one...

I'm not sure why the tag was different on these nodes, but thank you for fixing it.

These are residential roads.

I'm not sure where you found East Calabrese Lane, but the street is actually named East Bellalucca Lane.
