No limit on BitMinter. Run all your machines as one worker if you wish.
Thanks Doc! I doubt my GPU's will return to your pool unless BTC becomes the most profitable GPU coin... and even if it does, your pool was the first pool I joined and stuck with when I started 18 months ago, so I have created workers for each rig already on BitMinter:) However, my singles will be on your pool.... if I ever get them :-P
I assume I'll just have to test it on the other pools and see what happens... Seems it shouldnt be much of a problem from random threads i have read.
