I've talked to Luke-Jr and he said, that he wrote the core of pushpool.
Incorrect. I wrote 99% of pushpool.
As far as i know, jgarzik wrote the pool. What luke meant by that, is that after he set up the pool, he wrote the "core". I find it hard to believe that since he till this day had no front end(although i still know not what he meant by "core").
I also want to know, after i start pushpool. What tables must be made and their structure with their datatypes.
How does the pool pay the user's earned Bitcoins(does it come out of my pocket?)
