8th Grader Suspended for Using 'net send' Command

HRH King Lerxst writes: "The Fort Worth Star-Telegram has an article detailing how a middle school student was suspended for three days for 'hacking.' His hack? Sending a popup message to the other computers in the school...from within the shcool." The 8th grader in question used the "net send" command to send a single word message ("Hey!") to the 80 machines tied to his school's network. How this can be construed as "hacking", I leave up to you.
