Slackware was my first Linux too. I remember making the installation floppy disk set. And then it was my first introduction to running a computer others could remotely control. After learning how to dial up AOL from Linux then join an IRC chat room, I was immediately "pwned" by someone in that chat room who guessed my root password and rm -rf /'d my entire hard drive. I was probably 8 or 9 at the time and cried.
Did you re-install and continue with Slackware after that?
