I just have a question regarding solved blocks. If a person's miner is active are they ensured to at least receive some sort of reward? My miner is currently GPU mining all night with your service and I noticed the odd reward where it says "None" even though my miner is active. i.e solved block #1003 to #1012 I'm reward, #1013 no reward, #1014 to 1017 reward, #1018 no reward. I did noticed in the case of #1018 the number of shares is very low, does that just mean I didn't receive a getwork for that block and therefore didn't participate? Is this intended behaviour?

Thanks for offering a great service and I agree donations should be enforced.
