I am probably gonna sound like a kill joy here but I don't mean to be. Would a scoreboard not be infringing current T&Cs set out by Bohemia for running a server? As you would be using the logs for something other than cheat/hacking prevention? Just don't want you guys getting in trouble with your server host or Bohemia.
@theZohanYou brought up a valid point. But I think eventually Bohemia will change this policy when DayZ moves into beta. The worst thing that could happen is that we cannot start the leader board at Christmas but at Easter
