The OP has edited this question. It seems properly phrased as a PM question now; in fact, I'd like to give an answer to it. Can it be taken off-hold now?
Technically, yes. However, for a number of reasons outlined below, I'd like to see this particular question remain closed, and the heavily edited question the OP inspired the community to create should be moved to a new question.
Reasons Not to Re-Open
A question can be re-opened by flagging for moderator attention, or by having enough re-open votes. However, in this case, there are some interesting meta-questions that (in my mind) argue against re-opening it:
While this is now a good question, has it been edited so much that it no longer resembles the original question?
To me, it seems like it is now a completely different question. That's not really what editing is supposed to be for.
If the question is no longer the original question, should the OP receive upvotes (or downvotes, I suppose) for a question that isn't really the one originally asked?
From my point of view, while an improved question makes the Internet a better place, a different question ought to be asked as a different question. I would recommend someone who cares enough about the new, on-topic question ask it as a separate question and gain some rep. The old question can eventually be linked or deleted.
What should we do about invalidated or obsolete answers to the original question?
One person already answered the old question. If we re-open the question, the answer may attract downvotes or become obsolete if it no longer directly addresses the newly-edited question. While this is always a risk with editing, we shouldn't set out to deliberately obsolesce a well-intentioned answer.
