Has anyone received their payout from the multipool yet?
Yes, I got mine.
I did too but I don't believe I got my SHA256 shares added into it.
I'm not there yet, I have something else I have to finish out with my gridseed. That being said, I've mined through chunkypools in the past, and they have always got it straight sooner or later. If they have some problem with payouts, talk to them. They'll pull the logs and fix it. They're a decent outfit.
