Never mined at this pool, okaypool is fine judging by previous coins I mined, I can recommend you allpoolz.com, seems to count much better coin,
I mined sumpool.com few hours and have 10K unconfirmed, switch to allpoolz and after 2-3h I have 4300 unconfirmed and a bit over 5k estimated,
keep in mind DIFF spike high over 300 now is falling down to 16?! and slowly will settle in range 5-50 I queues. This coin have very long confirmation time I think even higher than Blackcoin, judging from time I wait for confirmation.

My hashrate is 1Mh/s (2x270 MSI) , second rig in OFF due lost control on remote pc. I am abroad no way I can resurrect
