Is there a way for a user to change their vote?
I am using the gallery for people to pick narrow down their best images from a photoshoot and eventually narrow it down to their top 10. So people may start off with a 4-star image and they then decide that they want to make it 5-star etc.
Unlimiting the voting is one way, but that takes the average vote. I.e. a 5 star and a 1 star vote = a 3 star vote.
