I've been waiting for nearly a week for the remainder of my BTC to be exchanged.
Repeated emails to pool mods go unanswered. No excuse for this!
I'm getting the distinct feeling there's something dodgy about this pool so I've now withdrawn my funds, writing off the unexchanged BTC so at least I don't lose it all.
Given the amount taken in fees by hashcows it's a bit rich to treat miners like this.
Keep my cryptocoins you chisellers, I'm putting my hashpower elsewhere from now on.
