I guess it will be better to allow someone to check someone else's reward in case the user wants to find out the reward of another user.
function checkReward(address _who) constant returns (uint256 _reward) {
/*
Withdraw of the amount of the prize (it’s only informational).
@reward Prize
*/
var voter = getVoter(_who);
return voter.rewards;
}
