Not Getting shares but have decent Hashrate
What are you mining? If I'm still right old days 200mh/s was enough and 5ms/s also, but today should be already dead not? 

It is still possible that pool didn't had luck in solving problem and you got no reward.

I just realised you wrote Slush's pool, which means you mine BTC, which means 
pool has now 36.21Ph/s which is  36,210,000,000,000,000 hashes/sec 
You have 205,000,000 hashes/sec  that means 

(36,210,000,000,000,000/100=3,621×10¹⁴=1% ->205000000÷3,621×10¹⁴= 0,000000566%)  

You got 0,000000566% of pool mine, if they will mine 100BTC, it will be 0,0000566BTC for you per day... It is still not enough per day to make transaction... Wait a month and let us know here...

With having pool not luck seems not possible since they have written:

Luck 1,7,30days : 128%, 121%, 89%
