72GB/S BFL.....I HAVE ON AND OFF BEEN MINING SLUSHES....but it said I had shareson my account but on each block found, no shares...and nothing registered the whole time either
Log into your account at Slush, check that your worker credentials are EXACTLY what you entered into your miner. Check that the pool IP address is entered correctly into your miner. Look at your Account page, confirm that this particular miner is reported as hashing: in the Workers area check the entries for Current shares Score Last share at Mhash/s* of this particular miner. If you don't get anything there, you won't get any credit/reward for your efforts.
Check your miner's display and confirm that your shares are accepted by the pool.
Note also that Slush has a unique 'anti hopping' algorithm, that gives full weight to the shares contributed towards the end of the block. If you paused mining a few minutes before the end of a solved block, your reward may suffer badly (on the other hand, if you joined a block late, but stayed till the end, you'll get almost full reward based on your proportional contribution).
Cheers
