At university, we had a whole IM network built around "write" on a multiuser *nix server (over the past 20+ years, the university netsoc has run services on freebsd, solaris and various flavours of Linux). We also had terminal based maps which would allow you to find friends based on the IP they logged in from.

See https://c-hey.redbrick.dcu.ie/ for the wrapper around write. These days students seem to prefer discord. :/
