Via Preferences, heading Betafeatures you can switch on the Content Translation tool (CT) at the very bottom. [In Dutch Wikipedia that is.] With a mouse-over at Contributions one gets a menu with Special: ContentTranslation; I have prepared a number of English and Danish articles and translated the German article Reptiloide into Dutch Reptilian. So far so good.
However, when I tried to go the other way, the thing turned out to translate Dutch into Dutch if I specified nl→en or nl→de. No cause or reason was given; the thing worked somewhat, as categories and templates were translated into their English and German equivalents. I could not translate into Danish either, but at least that could be suspected because the mouse-over was missing on the Danish Wikipedia. Spanish did work in two directions. After a lot of searching I found a possible cause: according to User access levels, heading Extendedconfirmed I am still eleven contributions short of the right to use the CT.
Is there a good overview of the possibilities and impossibilities somewhere? Or can there be a decent error message at an early stage? I've been looking around for goddamn hours and still don't know where I stand!~~~~
