a. Some stupid person got my refund email shut down. Probably the same person who has been sending threats and attacking the refund process. I don't know why people are fighting the refunds. There is nothing to gain. Everyone will be paid back. If this was a scam I would not be here and would not have repaid more than 100 bitcoins so far.
That means our spreadsheet is quite wrong. The good thing is, we will get fully refunded faster than expected. According to BTC-Arbs it was less than 500 BTC in total. Refunded more then 100 within 2 months. So we may all get refunded till summer next year.
