Why limit what pools/coins your users can mine? If it's an API thing, just tell them YIIMP only pools or specify brands. As for coins, just allow them to add to the list. GPU miners want to have options. Just 2cents. Love the look of the software but it feels limited for no reason?
We have other approach to development. So adding the pools ans coins takes some time.
Minerboard has options for gpu. What makes you think that doesn't?
What limit do you mean? The coins, pools and algorithms will be added gradually. There are no other restrictions.
