So far this looks like a incredibly heavy early-adopter coin. For example, the first few block rewards were 10 second target, with around 5000 coins per block. Now the target is around 10 minutes, and the reward is about 250/block. I've mined this coin at 7+ GH/s for a day, and I only have around 200 coins.
Judging from the mechanism, it seems that the more popular this coin becomes, the harder it will be to generate new coins. This seems to be a very sneaky pre-mine mechanism to me...
It was easier at the beginning before the difficulty adjusted, and before the network hash rate began to grow (as with most coins).
I still have a few EmerCoins that I can share, if people post their addresses..
By the way, I managed to get cgminer working on pool.emercoin.com. Thanks for your help.
