I remember Novell, as a student, and a little bit as help desk. We had access to do basic things like reset passwords etc. It was a decent system for it's time though, but once AD became more of a thing it kind of lost it's purpose. Also, remember Groupwise? That was basically their version of Outlook/exchange.
And since we're going down memory lane, remember Corel suite? That used to be huge in schools too.
I can still remember putting in my Novell username and password, logging in to the Pentium 1 computer, then opening Word Perfect to do my assignment, and hope it does not crash. Back then software was so unreliable lol. It was driven into us to save often. To this day I still hit CTRL+S passively as I'm working on anything.
