For those that don't know, September was when all the freshmen would get their first access to the non-commercial internet in college. It was a pain because they (we) had to learn all the nuances of how to interact with the people already on it. Newgroups, IIRC, etc. Eternal September is the term for when the internet went commercial in 1995.
Wow that happened 27 years ago. Time does fly.
