Call them whatever you like to call them

if you are referring to the old Bioware community Neverwinter and Neverwinter 2 (The former made by obsidian) the multiplayer persistent world servers are still up and active and still lack the term 'toon'.
a list of a few hundred active servers may be found at: http://www.nwnlist.com/

I'm pretty sure he's talking about Neverwinter Nights from around 1991. It was a text MUD that ran on the AOL servers. The Neverwinter nights 1/2 games that you're talking about came about because of that old MUD.
