..... 2. "Odra" is the original and the true name of the river.
I doubt this. I would guess, that the original name was neither Oder nor Odra, but something completely different. There is nothing like a true name. This is the same dispute as for many other placenames (Macedonia, Sea of Japan, etc.)
This is not directed specifically at you Mirko, but; The idea that there is "one true name" of /anything/ is a total fallacy. Names are not intrinsically linked to subjects - all they are, are abstractions that the human mind uses in order to index and store data connected to the subject.
So the only "correct" name for a thing in English Wikipedia is what is most commonly used and recognized by English speakers.
I've already told, that I would not mind, if we should decide to use the name "Odra". But I would like to place a decision in our Naming Conventions, so whenever someone changes the name again, we can refer him to that page and simply correct it without having a new chauvinist outcry.
Mirko.
This is already covered by: http://www.wikipedia.org/wiki/Wikipedia:Naming_conventions_(use_English) and http://www.wikipedia.org/wiki/Wikipedia:Naming_conventions_(common_names)
Therefore, as already has been explained, Oder and Neisser are the forms we should use.
