You quoted him saying that due to an error he would send payments on Friday.  Since today is Thursday and not Friday, its probably safe to say that he is not *yet* sending payouts.  I've been mining on Zpool for a few weeks (so still a newbie) but everything eventually gets paid.  There have been some front end hiccups and this payment hiccups, but still totally worth it to me for the returns vs other pools I've tried.
