I might as well post in here since the deadline is tonight. I scheduled with my opponent, Blue YM, for this weekend because he suggested it. I said in advance that I couldn't play on Saturday which, looking after all this, was the only day he could play. I suggested to play on Sunday but he never responded again. Looking at our timezones (he is GMT+2, I am GMT+3) it is pretty amazing that we couldn't get our series done. I don't want to call activity because to be honest, I don't deserve it. My opponent deserves it even less. I don't think either of us deserves to get an extension because we couldn't get our series done on time even with having great timezones.
So I will leave this up to the host. He can either give activity to one of us (I don't deserve it but he certainly doesn't deserve it) or coinflip this series. Not like either of us is going to do well in this tournament so might as well have the coinflipper get the win as he already got it.
