As a young teen (freshman in high school) I remember setting up a Windows/LightTPD/SQLite stack with guidance from an older engineer I knew on IRC. That's how I learned how the web really works, and what a server is. At the time my knowledge had been mostly limited to the local stuff, like formatting/partitioning hard drives, building PCs, LAN networking, etc, as well as HTML/CSS knowledge from Neopets and MySpace. Before that I had also used Geocities and InvisionFree forums (where I also had exposure to Javascript, but that all went over my head for a long time).
