A small voting system, which you can use ingame.

Code:

#define SKIP_ALLOCATOR_SHARING 1
#include <ScriptSetup.h>

void SetupVoteBallot(ScriptMgr * mgr);

    VOTE_NO,
    VOTE_BLANK
};

int voteamounts[4];
int originalamounts[4];

ostringstream stream;
string question;
string answer;

TimedEvent * te;
