Well Sebastian sir, I am taking your advice and I'm on windows 7 so right
now I'm downloading virtualbox and xubuntu. I don't know if there is one
that you guys recommend. Well... I am new to all this stuff so I'm asking
you to please help me on the subject like after everything is up and
running on the computer, what other steps do I do afterwards and forgive me
like I said I'm new ot all this stuff because I want to be able to find my
link capacity when using SQM. and Thanks for the help!
