When I vote on challenge entry, I often want to tell the photographer something, either a compliment or a suggestion. I don't want to have to wait a week and then go hunting through the images to leave a "first impression" note. So, I'm really glad that I can leave a comment now and not later.
OK, so we can see the comments. I'm not going to lose any sleep of that . I mean, c'mon, do you really think it's going to affect the outcome of the challenges? Considering the number of spoiler votes being cast, I don't really think it's going to screw up anything. When push comes to shove, I'm more interested in the conversation around these images than deciding on a "winner."
DPR, thanks for allowing us to make comments during during voting!
