in my senior year in HS i got suspended from "computer use" for the rest of the year lol. i had a programming class which kinda sucked but i didnt need the credit to graduate anyway so i just slept in that class, C++ is boring anyway.
but yeah i was using netsend in class to freak out some of my friends, like popping up on their screen pretending to be an admin if they were on a website telling them to get back to work. so i told them it was me and theyre lke whoa howd you do that, so i show them and they use netsend *, which sends it to EVERY computer on the network. at first it was just "hi",
