Recently, I flagged this answer as 'Not an answer'.
Now, after looking at it a couple of times, I have realized that this is an answer, just it is extremely badly written and needs editing.
So my question is: how do I take back a flag that I have put on a question/answer? If this is not possible, could this feature be implemented?
The main reason why I want to take it back is so that the moderator queue is shorter. Also, to reduce the number of declined flags on my account.
EDIT: It turned out my flag was deemed helpful after all. I would still like an answer for future reference.
