I'm running a photo contest. It's a dot voting contest and I've allowed each participant one dot (one vote) which they can use on an their favorite image. When I look at the Analysis page and check Ratings, I see that in addition to a count of "1 dots" for each image, there's a "0 dot" count for many of the images. What is a "0 dot" and how do the images get a "0 dot"?
By the way, the contest is going great. Very happy with the pollunit product!
