Hey, thanks for giving the pool a try.
We've been having real trouble getting the MinCoin wallet to sync to the correct blockchain. It was mined earlier today but on a bad fork, so we disabled it and covered the losses that were incurred from it - we are taking the hit for any issues that are out of the users' control. So in the meantime we're being very careful with MinCoin until it's back on the right chain, but it's high on our priority list to get this coin sorted.
GrandCoin is reporting a problem - will look into it.
Thanks for the feedback - we're still working hard to get the pool as profitable as possible.
