"Turn off the light."
Translation:E hoʻopio i ke kukui.
Only the "My answer should have been accepted" report is of any value. If you are certain that what you wrote was a correct and valid way to translate the sentence with no errors, then it is the best way to tell them they are missing an acceptable variation. They will be notified of exactly what sentence you attempted. It is easy for them to add that variation in so that next time it will be accepted. And you will get an email notifying you that they added it.
All of the other reports basically just say, "something is not right" and so are completely useless. For any other problems or questions, the sentence discussions are the best place to ask about or explain the problem.
