I've moved everything back to BTCG where I make less than Slush but I'm informed at all times and issues are not only fixed but communicated as well.
You'll end up making more on Guild. 1% fee difference doesn't make up for paid orphans and NMC merged mining. Assuming you're on PPLNS (which I would certainly hope you are).
Been curious but haven't looked into it yet... Can anyone explain to me NMC merged mining? Is this a scrypt coin for people without ASIC so they can still produce in a pool?
