Hello, you can add both natural=tree and tourism=attraction to the tree, there is no problem of it having multiple classification tags.

Hello, barrier=* tags are used for gates that inhibit access. For railway crossings please use crossing:barrier tags:
crossing:barrier=*

Road numbers are tagged using "ref=DCxx", take a look at how I tagged it now. I see that there are a lot of communal roads in the area (DC81A...DC81V), if you have local knowledge it would be awesome to map them all :)

Changeset reverted in #103065416.
Bad Russian name for river.

Is this correct? From my observation, in English the most used spelling is "Tisza", followed by "Tisa"; "Tysa" is the least used.

Seriously? What is this change:
relation name:
before=Дністер / Nistru
after=R30 – Tudora – Palanca – frontiera cu Ucraina

This is a river, not a road.

I also saw some problems in the other changesets, regarding naming, mixing the tributaries name (white/black Tisa) and proper name (Tisa) in different languages and different segments (for example naming the entire river "name:ru=Чёрная Тиса", name:en/ro/uk=Tisa on the White Tisa part and "name:cs=Bílá Tisa" on segments after the confluence.

I'm going to revert of your changes and I'll do the naming in every language myself.

I have commented on one of your changesets in which you have deleted those tags. If you didn't see the message I am copying it here:

"Hello willisturm, It is a good think that you are doing quality control on the map, but please check with the local community before deleting a big amount of information from the map. In Romania, we keep a lot of information about the state of highway construction on the map. It is something that a lot of people are interested in and even if those are non-standard tags you shouldn't delete them without consulting."

A wiki page regarding the tags used in Romania regarding road construction and road quality is WIP and we will explain what tags like highway=lot_limit mean.

Hello, what is the scope of this changeset? I see that you dragged some nodes far from where they were supposed to go and deleted some tags.
Tell me what you wanted to modify and I will help you.

Hello,
I saw that you deleted some neighborhood boundaries in Ploiești. Is there something bad about them?
I have re-added them in changeset #102947106. Please be more careful.

I double-checked and data in OSM seems to be correct. Those roads are clearly inside the Romanian boundaries and give wrong addresses.

It seems to be a problem regarding the app/site where you ask for address. Can you describe me where do you query the address information from?
