[fcha]

I did search many forum even Blizz forum, there have no blue post are 100% allow multiboxing and ISBOXER.
In the meantime, i got a Blizz whisper when my toon in BG AV and said - "do not use any illegal software to process game or u will get ban. " something like that.
So i report to GM and send them the screen capture and waiting their reply.
Let see what i can next....
