check the batch file link in my sig. lots of good info.
near the bottom of that post is a link to my original batch post, with a LOT more info.
profitability is based on your hashrate and algo you mine.
be sure in your password to supply the payout type; as well as the algo name you are mining. ('c=btc,skien' as an example)
I have batch files for manual selection, or for profit switching available. I should be finishing my updated version of the batch sometime soon.
To see how an individual batch launch for a single algo would be done; check out my how to normalize section.... it has batch examples.
