I don't remember if I said, but I got started learning this stuff from a networking program someone had written to allow you to play DOOM over the modem, IIRC. So thank you to whomever that was!

And thank you for writing the networking guide. I found it in my early teens when I was interested in learning programming and wanted to go beyond the basics to do some more interesting stuff.

It helped me write some chatroom bots for things like IRC and battle.net in the early 2000s, which fueled the hobby even more and eventually turned it into a very good career. :)
