jmgir: Yes and again a 1/2 star rating, this is annoying. The host should contact the voter and ask why this low rating. Thanks.
Seems like this is the case pretty much with every challenge. I always find that there is someone who is low rating the best pictures (on purpose ?). Maybe this is another contestant who is trying to game the challenge by low rating pictures that he/she deems are better than their own entry.
