I found out about bitcoin when a google search took me to a thread (
http://www.jupitercolony.com/viewtopic.php?f=57&t=11421) that laid out how to set up the program. When I registered with bitcoin, it didn't prompt me to create a suffix to my username and it didn't generate one for me afterwards, with the result that I'm completely at a loss as to how I can start mining. Any advice would be most welcome.
