MOO for poetry pedagogy, 1994-1998
From 1994 until 1998 or so my poetry class used a text-only virtual university that we built called PennMOO. (It was, obviously, a variation of MOO.) I held open online office hours, we had class there on the day of a snowstorm, we hosted poetry slams, and we even built and used a skating rink. Someone studying MOOs contacted me about this and I found an old web page with links that mostly still work.
