2) What are the advantages of getting Human status over the network? Apart for an extra flip, I see only that he can miss the short session, but he can NOT miss the long session. This is kind of weird because if you are not at the PC at the time the validation starts, you most likely not be around for a while, so you will miss Long session too. I don't see this an advantage.

5) Will be the additional flips made by the Validated/Humans rewarded?
