Since we have a 'should be asked on ELL rather than ELU' (or words to that effect) close-vote reason, it would be reasonable to have some knowledge on what the people at ELL deem suitable questions. I rarely visit the sister site (and on a couple of occasions, felt that questions there should have been migrated to ELU!)
I've just voted for migration of the 'Which is correct: I needed to see you or i wanted to see you?' question from ELU to ELL, but I wonder if I'm doing our colleagues there a disservice? Is this also too basic for ELL?
I'll transfer a deleted comment to include my approach to answering (or otherwise) a question; this comment was in response to deadrat's "Have we started giving a damn about what low-rep posters want...?"
My 'line of approach' is almost always (1) Has OP made the slightest effort to tailor their question to ELU recommendations? If so, (2) Is it still obviously off-topic? Whether or not, (3) Is there an interesting and on-topic point for discussion, either overt or in what may well be the 'question behind the question'? (4) If so, is an edit preferable before an answer? If I reject at the first stage, I will still consider submitting a related question myself.
