To my great dismay, cloudhashing.com has gone "off the air" with communications. The vaunted Reinvestment service they have is non-operative, and no explanation has been given publicly or privately to me regarding the RRP features of my existing contracts.  We are now 17 days into contracts that should have been enabled as of Dec 1, and I am not receiving the mining benefits per my contract. I urge new users to hold off on buying new contracts.
