+1 good question

i can answer. my pool change config worker difficulty daily not fixed. Worker difficulty fact follow for Network difficulty.
Thanks. This helped me a lot setting up a pool. I changed the difficulty to around 17.000 and finally the pool is getting blocks.
The pool is available on
http://qcnpool.org. Mac users might want to use the
Mac OS X GUI miner that can be downloaded from the home page.
And somehow the pool seems to be stuck again...It looks like we should all mine at minin.gs if we want our hashes to be worth anything. Is it ok if 'one pool mines them all' or could someone point out how to get the other pools going?
My configuration looks like this (difficulty was 17000):
