Yes, the email function is down at this time. We are working on it and should have it back up this week.

If you provide your address, I'd be happy to look into the discrepancy with the reported profitability versus what you have been paid. If you don't mine continuously with us profitability can vary greatly depending on how lucky we get with larger coins. This will even out over the long run and as the pool hash rate increases. My personal accounts are very similar to the overall pool profitability.
