Do you know what has happened with the translation of the document "Firebird 2.5 Language Reference" from Russian to English?

They had requested for donation with the promise that their work would be ready in February 2015.

The donation was made, now it is September 2015, but without news about the document translated.

I want to translate from English to Spanish (and for free, I don't want to receive money for that). I don't know much Russian and the Google translator is not good from Russian to Spanish.

Greetings.

Walter.
