It would be great if the system could detect the language of a question, and pop up a little notice:
Please note that this site is in English only
Your question will be flagged for moderator attention. Please help the editors by spelling carefully, so that they can use a translation program. Thank you.
(and in their respective langauge)
Then, the system should automatically flag the question with "translation needed".
All of this should be possible using the google translation api (which I know nothing about, so I might be wrong).
What do we think? Is that something that could work?
At the moment, people are quite quick to translate questions, but they're often stumped by complicated grammar (i.e. Google translate is).
