I´ve PMed Pyramining something like last April days. I have a trouble with one of my accounts, with an Instawallet payout address, and asked for some solution.  He answered me 10 days ago,  asking forgiveness for the delay. He said he is being very very very very busy with ASIC r&d in these days. If he is not answering, i believe is because he is really working hard to get ASIC working,
