I mentioned this before but received little response so I thought I'd post again and add to it a bit.
A report error button could be added in to allow you to use readers as editors.
You could add a spirit stone reward for the first person to report a specific mistake/error and if people post things as errors when they are not 3x in a row they could not receive their daily stones for a day or some such to prevent abuse with escalating punishments for people using it to waste editors time.
