ricky - get a "test PC" - ie:- a setup, that is *not* 'normal use' machine,
it can be a desktop or a laptop, But- it Must be something that you can "play with".
without having to worry about crashing it / killing it / stuffing it completely . . . .
the use that remix cd - or any other 'live cd' and "just play around with it"
- that's the Best Way to Learn
- eventually - install that O/S to the "test hdd" - & "just keep playing with it".
- you can do this repeatabily - with anything that you come across.
