One of my questions was recently put on hold. This was the first time it ever happened, so I didnt really know what to do. I improved the question to quality standards, but it wasnt put off hold, and I didnt know how to get it off. So I decided to make a new question which was a repeat. Sufficed to say, the same people who put me on hold last time came again and started yelling at me, flaming ensued, etc.
I did not find out until after that there was a (very hard to see) reopen button. The on hold message already instructs you to improve the quality of your post, so it would be simple to just tack on "and then press reopen to start a vote" at the end of it. It would have saved me some hassle and a flame war :)
