Related to this question: should we answer off topic questions, I was wondering if we should edit obvious spelling and grammar mistakes on questions that seem like they might be off topic, even if they haven't been closed yet.
For example, I was looking at this question: question about wild dogs, which seems like it might be off topic on the basis of being story-based. However, I went ahead and cleaned up the grammar (mostly extra spaces and weird punctuation) to make the question more readable anyways. What I'm wondering is this: should I worry about grammar/spelling on a question that's liable to be closed?
On the pro side, it seems like if the question is later edited to be more in line with world building, grammar edits will help to improve the quality of questions on this site, which is a good thing. On the other hand, if the question is not reopened it may be wasted effort, and if the asker is editing their question anyways to make it more of a worldbuilding question, it may be better to wait until the question is in its final form before cleaning it up. What do other people think?
