History of the term Plural
"Plural" of course is an English word, but used as an identity…
Crisses has September 12, 2000, from Arhuaine of Doltaghey House on the Elven-Realities email list, regarding the "otherkin code again":
Would need to unzip email archives to go back further in my emails. Doltaghey House is one of the first people we heard use it (by memory) and they had the positivelyplural.myforums.net forum (announced July 9, 2003) then registered the domain PositivelyPlural.org and announced the registration to us on April 7, 2004. — Crisses
Following up with Casteylan& — formerly of Doltaghey House (they changed system names, and system members, but Cas is still there) and now on Reddit as Downtide — they did not invent the term "Plural" and may have gotten it from Dark Personalities or someplace else. We Crisses still think they're the first to have mentioned it around us. We are still poking around the web and trying to sniff out a trail to locate documentation or people who know where it comes from.
