I will NEVER use
http://www.miningpool.co . Started off good but then 50% went orphaned and then all of a sudden it just stops for 1,5 hours before everybody is kicked out. Worst. Pool. Ever.
Pretty much sums up my entire experience so far. Maybe me and my 25khash/s are bad luck. Seems that every icoin pool i join dies...I was on ic.mepool for the premine, and its dead. I still have 5 coins pending there.
