I saw that when you going to participate in a contest you see your entrieS like 0\1. why it's not like a checkbox, you planning to allow to one account to participate in one contest many times?
I think they didn't thinking a lot about this, i mean about checkbox or numeric, it's just their vision of interface that can be changed, because if they decide to do that you say it will be not so good. I'm don't see problem in this but it's strange.
