the good news is that the devs who are taking over the pool sound confident. There was a mention they may start internal testing soon.
PoS has not YET been implemented. It will be implemented shortly!

"PoS should be kicking in very soon now."
When you coins have reached maturity for PoS, it will then be listed as PoS coins. If you have held ALL coins > than 8hrs, than your stake should = your balance.
Hope that helps a bit!
