What do we do if (say) a non-native user tries to ask a question in French, and there are glaring errors, or just grating ones in their question?
Encourage them to ask in English instead?
Or spend our time correcting everything?
(To quote myself: "And I'm totally against non-native speakers asking questions in the 'other' language unless they're really proficient, because you either end up with 'crap' French on a FL&U site, or need full time editors to go and clean it up, render it idiomatic etc...")
This will probably come back to haunt me some day :)
