I distinctly remember that Freshman year, we were told in some big auditorium, during onboarding, that we should start using our university-provided emails as our primary "professional" emails.

Someone then asked what happens when we graduate and lose access to those emails, and they didn't have a particularly good answer.

I think that was also the same onboarding where they passed around a piece of paper for us to sign in with our name and social security number.
