Changing the star numbers or rating

This is a question posed to someone who is involved with administering the site or anyone who has ever wanted to do this.

Is it possible to change the rating you gave a story after you have done so for the first time? An example would be you have read a story and given it four stars and after reading it again you feel it is actually worth five stars or maybe only three stars.

Please let me know either way.

Thank you.

I don't think so. I've tried and it wouldn't change.

Thanks anyway.

Nope. one vote, one time.
