Very nice landing page!
You are paying your users 6,000 litoshi for every 1 million hashes. This converts to ~99 satoshi per 1 million hashes. I highly recommend using
WebMinePool instead of whatever you are using now. They pay a flat rate: 201 satoshi per 1 million hashes straight to FaucetHub in btc. If you were to connect this to FH, the only fee you would pay to payout your users is the .5% exchange fee FaucetHub has, because you pay out in ltc. Let me know what you think about WMP!
