Hey, been through these forums a little lately, mainly the galaxy s thread. so thought I better say hi!

I've had a strong interest in IT since I was 12, so 8 years now. Most of my interest is in the networking side of things. maybe something yous can help me with?
I want to go back and study, only have NCC3. So was wondering what the best way is to get into networking?

Was looking at this:

I want to setup networks, administrate them etc,
Wondering what the best course to go for is, thought I had better try and ask around first!
Is there a demand in networking?
