First you have to do: Login into your LEADER Account and type in game: /f a (Leecheraccount)
Second thing: Login into your LEECH Account and type in game: /f a (Leaderaccount)
This is crutial so that your leechbot receives game messages via whisper.

Leechstarter:

var leaderAccountName = "ganon";
var leaderName = "Ganon";

Charconfig:

    NTConfig_LeechBo = true;                            // Set false to disable BO & BC cast by leecher.
    NTConfig_LeechExitDelay = 500;                      // Delay before leecher exits game after leader in milliseconds.  Use this to stagger leechers exit times to avoid crashes.
