I have translated this song from Russian to English. Can you correct my mistakes?
This is one of the questions in the proposal. Asker then wonders if this kind of question would work well for Q&A site. I'm surprised by the number of 'great on-topic example' votes on that question.
I don't think help in translating more than a couple of sentences is suitable for this and other proposals; it's better done at http://translated.by and similar crowdsourcing sites, where a lot of people add and edit their suggestions. Here in turn we'd obviously have a lot of answers, and accepting a single answer would be almost impossible due to variety of possible translations.
Proposal: English-Russian Exchange
