I won't flame you about that, but I will point out that your mailer 
sends out long lines. Could you look into wrapping them at 80 columns?

I've never found it the best way to learn because:

a) you lose some of the experience you gain from things you need to 
learn during installation eg. finding the right driver for a network 
card because there's a "virtual network card"

b) it's not a fair comparison of how efficiently Linux will run on the 
hardware, because it's running virtually. "Oh, look Linux is slow.." no, 
virtualized OS's are slow, especially when run from a slow host OS.

c) if you're using up the space on the drive for a virtual disk anyway, 
dual-booting is a better option.

If you don't have the extra hardware, why not dual-boot? This way forces 
you to get familiar with Linux without allowing you to resort to back to 
bad habits like Windows :-p

Two ways which will work in most Linux distros, as root:

1.

(This might be Debian and/or Ubunto specific.. not sure)

ifdown eth0  # should not need this if it's already down :)
ifup eth0

2.

/etc/init.d/networking restart

(note that /etc/init.d/* are scripts used to start/stop services. They 
are run at bootup, depending on the init level you boot it-- default one 
is found in /etc/inittab. The scripts per initlevel are sym linked from 
/etc/rc$INITLEVEL.d/ )
