thanks for the primer.
The miner's task is to find a special combination of numbers, hash of which will be lower than specified value. This happens rarely, so miners are submitting not only the winning one but others that are low, but not low enough, so pool can see that you are really trying and not just waiting. Each one of those results is a proof-of-work and we call it a share.
One of those will be low enough to create a new block.
i will write to you what i think i understand from your explanation. please let me know if i miss something. so 1 share = 1 hash found. no all share/hashes are winning, but all demonstrate to the network that i am an honest miner. my miner is working at 1470 khash/s, etc. on coming up with a hash to submit to earn a share. some of these hashes are winning. winning hashes create a block. what is a block?
Sorry, not sure if I described it correctly in english

your english is better than my bitcoin-ese. also, i've earned 0.0006 BTC but nothing shows up in the bitcoin program which i gather is my BTC wallet. are payouts only made when i have at least 1 BTC? thanks again.
