Post in the thread if you have any problems, there a 5-6 people keeping an eye out to support new users.
MSCoins were only launched on the 10th January so there are still a lot of new people finding their feet.
I'm having fun with that Java miner before I eventually gut it and make it a real application - well, if I have time.
Great, let me know if you get something up and running.
Already did; slightly faster - but really, I may just run my own damned OpenCL through aparapi.
Go for it, it is still early days.
The MSCoin minting system is designed for other developers to come on board. There is a bog standard minter bundled with main Nxt software to bootstrap the system that is already falling in popularity. Already, the "NxtMint Java Minter" thread you posted in on nxtforum.org is one such developer that has started his own minter that is supplanting it (the dev of that has nothing to do with the development of the Nxt core or technology).
In theory, minter devs will compete with each other to design the best minters. If they can figure out a way of selling them without people pirating them (possible using data stored in the blockchain as a checkpoint/licence perhaps? IDK), then they would become the new ASIC manufacturers equivalents of the minting world.
