I see a new user who's got a gem of an idea that just isn't articulated well for a SE-type question. The question goes on hold. My fear is that more often than not, that person is just going to go away in a huff. I fear it's even more likely if they do in fact make (what to them seems) a significant change, and there's no immediate release from Question Jail.
Someone who's been around the block a few times can see how to get a question in under the wire here, and may have "edit powers". The problem I have is I'm less willing to invest the effort if my editing, too, were going to languish around as long as the new user's first edit attempts typically do.
Q: What is the un-hold process? Does it take a mod-majority vote, or does editing release a question automatically?
