You've gone about as far as you can go with Windows 95/98/NT.
You're in a box that Microsoft built. It's time to get out.
You're ready for a real operating system for your pc -- multi-user,
multi-tasking, Internet capable. An operating system in the great tradition of Berkeley unix, with hundreds of ready to run, free applications.
You don't just want to connect to an ISP....you're thinking of
becoming one.
You want to write your own bot, run your own web server, compile
your own kernel, hack the system code.
Make the world.
