I'm fixing them now.

Why only a "name" tag, what's this supposed to be?

Reverted (with other fixes) in 34684042.

This changeset only deleted a boundary line. I'm reverting this.

Please do not join boundary lines if you don't know which relations they belong!

What is this lone "limi" relation? Would you please write changeset comments, to let others understand what you're mapping?

Why do you delete the Turkey-Armenia border?

For libraries, use amenity=library.

Is this footway really named "Faixa de pedestre"?

What's the purpose of the untagged node?

A więc Bonanza jest na południowy wschód, a nie zachód. Jesteś jednym z tych, którzy mylą wschód z zachodem? Zgiń! Przepadnij! Zapowiadaj pogodę w TVN! :D A tak poważnie, dzięki za kawałek wartościowej informacji. OpenStreetMap jest po to między innymi, by gromadzić takie nazwy miejscowe, nawet zupełnie nieoficjalne. Nigdzie indziej jak tylko w OSM może się nietutejszy dowiedzieć, gdzie jest ta cała Bonanza, Kaczy Dołek czy inny Trupi Lasek :)

Do not glue building to the street please.

Na "południowy zachód", jak napisałeś, jest Bardo. Gdzie jest ta Bonanza? Proszę o konkretne współrzędne.
