DZ, as far as security goes, a potential hole here is that our bitcointalk logins could be compromised (probably much easier than a 2fa MintPal account) and someone could pm you claiming to be one of us stakeholders telling you to close out the stake and send the DRK to a different address than the payout addresses we initially provide you.
Because of this potential security lapse it might be wise to make the payout address also be the cash out address and then not enable anyone to ever change their cashout address. Or maybe we should email you now our own email addresses and you could simply send a confirming email if someone absolutely must change their cashout address?
