Hallo Schreck,
ich glaube es ist nicht klar, was das Problem ist.
Was meinst du mit GPS-Punkt, wenn nicht OSM-Punkt?
Kannst du die Koordinaten geben?

As far as I remember, you have to send an e-mail to the admin.

How about:
amenity=fast_food
name=Don Pedro
cuisine=pizza
Sometimes pizza service is only take away.
I would add
note=only take away

You could split the lake into pieces, like someone did in BG
osm.org/?lat=43.3947&lon=26.6674&zoom=13&layers=B000FTF

This was said to be bad, because it is mapping for the renderer.
But it looks better and it is obvious and generates serveral names.

Go into Potlatch ('Edit') for the area in question. Press 'U' for undelete. You'll see it reappear as a red line. Select it, then click the little padlock at the bottom to unlock, and deselect to upload it again.

Another way is the api:
osm.org/api/0.5/relation/id/full
Than convert osm to gpx e.g. with gpsbabel.

But thanks for the hint.

This looks like you should use
osm.wiki/index.php/Relation:multipolygon
The river border is outer and the islands are inner.

Unter osm.wiki/index.php/Donations gibt es Infos auf englisch.
Unter "International Donations" findest du die Bankverbindung mit BIC/IBAN.
Das ist seit einem Jahr auch nicht mehr so teuer wie früher.
Ich glaube genauso wie eine Inland-Überweisung.

Der/die Tileserver sollten eigentlich nicht so teuer sein, weil sie einfach gespiegelt werden können. Der Datenbankserver ist etwas anderes.
Infos: osm.wiki/index.php/Servers
osm.wiki/index.php/Servers/Upgrades

Weil du den Tileserver angesprochen hast und wahrscheinlich Mapnik meinst:
osm.wiki/index.php/Servers/tileserv

Der ist also gar nicht gespiegelt :-(

Es scheint aber geplant zu sein, weil
a.tile.openstreetmap.org, b.tile.openstreetmap.org und c.tile.openstreetmap.org
genauso funktionieren wie tile.openstreetmap.org
Es ist aber immer die gleiche IP-Adresse also gleicher Server.

Die stehen dann unter @SabrinaP als "Your friends".
Nur wenn du Sabrina bist.
Mit (evtl.) Bild und evtl. km-Angabe und Knopf "send message"

Warum gibst du tunnel=no, oneway=no, layer=0 an?
Das ist überflüssig oder?

OK. It should be shop=perfumery but this is also not defined.
Also there is Tag:amenity=bicycle parking but not Tag:amenity=women parking

As long there are tags like amenity=pub but no amenity=perfumery there will be a gender bias.

So maybe it looked like you draw it, because you edited it.
To delete ways in Potlatch you have to press Shift-Delete.
I have to lookup the keys too. :-)
Happy mapping!

Wenn ich auf einer Strasse klicke oder in den höchsten Zoomlevel gehe, dann sieht die Karte plattgedrückt aus. Sonst aber sehr schön :-)
Einmal rauszoomen hilft.

Do you read your own diary?

I removed all three ways.
surgeon: Do you have problems using potlatch?
Did't you know how to delete a way? Look at osm.wiki/index.php/Potlatch/Keyboard_shortcuts
Do you know, that changes don't appear on the map immediately? Normally it takes till next wednesday.

Why did you draw that road, if you think it's wrong?
See osm.org/browse/way/27846933/history

Very nice is this
osm.org/?lat=50.05494&lon=8.64226&zoom=15&layers=B000FTF
there are serveral roads invisible :-)
Also trunk_links
This seems to be only in some tiles and some zoomlevels.

The ticket is only about trunc/water and trunc/wood both are not nice.
I wrote about trunc/forest which is not in the ticket and looks even worse IMO.

Now highway=trunk is invisible if there is landuse=forest around. See:
osm.org/?lat=49.98323&lon=8.60327&zoom=15&layers=B000FTF
