I don't quite understand the change from admin_level=3 to admin_level=2. A value of 2 represents a country border boundary=administrative Is this based on data that used similar named tag?

Can you add details on what changed in the changeset comments? "Hildesheim, Germany" doesn't give enough information. It looks like the population number got updated node/18318938/history

Can you add readable comments to the changesets? Hundreds of comments "g" tell other mappers little of what you worked on. @Asensancho/history Can be as simple as "added buildings from satellite imagery"

Can I assume the name=Null is an import error on node/5740123588

Fixed via changeset/56700250

I see the rollback in changeset/53365582 from 11h ago. Thanks a lot.

Try the 'undelete' plugin for JOSM. It doesn't always work, e.g. when a way was meanwile edited but sometimes it's the fastest to get back the old version.

bei allen der letzten zwei Tage fehlt der tag. Ich werde http://qa.poole.ch/?zoom=11&lat=51.01845&lon=7.60832&layers=FTTFB0 nutzen um Drolshagen und Wenden grün zu bekommen, also den Tag hinzufügen, bevor ich andere Städte anfange

Does this island really exist or is it and the streets a mapping error?

Do you remember what this change was about? There is no changeset comment and no named source. 13 relations and 7 nodes in a 50x70km area were changed.

Is it maxweight or maxheight for way/67477605, way/32987403, way/32987400 ? '3.5' could be both for a bridge.

The tag 'aeroway=Tinshack's notes' and the 'history' tags looks like a copy&paste error on node/2888377577

Is eleven=yes an error? Is it electric=yes maybe? fence_type=*

Was bedeutet rule=1 auf der Treffurter Strasse? Ist das ein Vertipper?

On the Plum shop (node/3539249963) with hire=yes, do you mean they rent clothes (rental=clothes) or they have a job opening?

On way/360603353 I see teater=yes, but that tag doesn't exist. Do you mean building=yes, amenity=theatre (amenity=theatre) ?

I understand this is a border control. barrier=border_control

What I don't understand is what the keys
bordar = bbordar
family_head = bordar
means and how they are relevant to a border control.

Hi Gary,
Do you remember why you changed railway=rail to work=limit on way/185304899/ ?

Is this railway=dismantled or railway=disused maybe?
