Anyway! I have to congralute you for doing that. It's a nice way to reward people, even if PoW it's pretty broken now. Could you make a look into stratum difficulty too? It takes around 10 min for me to get full hash going on with my ti's once client is open, since difficulty is too low.

I hope i'll find a way to mine HMQ1275 more stable, im having some issues lately and switched waiting for the next update on PoS/PoW.
