Gentlemen-

I am currently setup with middlecoin.com pushing to this address 18iHQhr17PwQoAguYrxHDMF3ftLgA7Vbxi.  My hash rate is anywhere from 200-300kh/s with an acceptance rathe of roughly 98.8%.  I have been mining for almost two days now and not seeing any payout.  The table is just blank for BTC next to my address on the website.  Am I doing something wrong here?  I have a few 7950's on the way to get my has rate to about 2.0mh/s but I am concerned something is not setup right. 

Does anyone have any thoughts?

Any help greatly appreciated.
Jason
