I've already mentioned this to a couple of editors in the
/dev/chat chat, but I think it may be worth mentioning in a Meta post as well.
If your edit is merely a correction of grammatical errors or a cleanup of the question's markup, without addressing the actual reason the question was put on hold, then
- the question will likely not be reopened in review, and
- when the original author fixes whatever the actual issue is with the question, it will not be put back into the review queue, and
- as a consequence, the user will be denied the opportunity to have their question automatically pushed into the reopen review queue.
If a question was put on hold, there is no need to edit it, especially not to just remove a couple of lines of "Thank you" or "I'm a noob", or to fix markup or spelling (unless this contributed to the question being put on hold, which would be sad).
If you feel that you can actually improve the state of the question in such a way that it would be worth reopening, then by all means edit it, and then vote to reopen it.
This has been mentioned in discussion before, but I felt that it's worth pointing out again. For old discussions, please see
