A few more details, from one of the authors: "it started out life as an AMIS system, but we added an account system and message forum to make it look and feel like a FoReM system."
It was pretty popular in the Miami area, along with Carina (which was based out of Palm Beach). I used to run the non-XE version long, long ago. I'll ask around and see if I can find anyone who happens to still have it.
