I was a school IT tech for 3 years so I thought I'd proffer some words of advice in your new post.

Drop the skiddyleet crap as .:front2back:. points out it's hard to read and it makes you look like an unprofessional wannabe. School kids can smell bullshit from 20 miles.

When investigating kids like this, when you get the evidence to take it forward don't do it yourself. Unless you are a member of teaching staff you are neither paid or qualified to shout at or otherwise punish pupils. Pass it to a designated teacher ot the senior managment and let them be the bad guys.

Be polite to the pupils, never talk down to them or take the piss. If they decide they hate you they could make your life a misery. The children are never your friends it is a 'them-and-us' situation. they will be nice to you to get what they want and then they'll happily screw you over.

Be the grey man.

More seriously, never stay in a room alone with a single pupil. If it's unavoidable ensure the door is wide open.

Teachers are arseholes. They will talk down to you and treat you like a skivvy. Don't be scared to put them in their place but never shout and not in front of a class. Generally they are idiots also but try not to talk down to them either. You are the professional round here.

Never ever, underestimate children. Every school had a prodigy or 3. You might be clever but you're no match for 100 kids working together to screw up a network.

Try not to let your mouth hang open too much when the head girl comes in asking for advice in her hockey kit. I failed that one.

apart from that enjoy the job. It's a good grounding for a lot of IT work and security work. you'll get hit with every attack known to man as the kids desperately try to get to pr0n, ringtones for phones, games or just to break something for the hell of it.

The software you'll be forced to run could be 15 years old (I had to fix a 20 year+ BBC master) and you'll be expected to be a guru in everything from WMI programming to photoshop.

Geek kids will ask your advice on badly modded pcs, teachers will pay you to fix home pcs. You'll learn a lot of people skills too.
