I broke through our Novell's systems "defences" numerous times. Our IT coordinator hated me (somewhat rightly so), and came at me wanting blood... But luckily I was always a good student, and friendly with the vice principal (who had fielded questions about what I was doing on the PCs when I was in primary school, he was the principal then), so the last time I was banned from using computers on school grounds for year 12, and that was the end of it. My final sin? I gave Quake 1 with the Darkplaces engine to a friend, who promptly transferred it to every computer. The IT coord decided it was me who did it, even though I had no idea it was happening. Oh well, all worked out in the end :)
