As an FYI, the original Elfinkind Digest mailing list - the one where the term "otherkin" was coined, and all that - has sent out a "last call" message. It's shutting down and telling its membership to send in any final notes for one last compilation/digest to be sent out at the end of the month, and then that's it. 1990-2018 and... done.
i can’t find a source on this, but i assume that’s because the message was sent to the mailing list itself, and not outside of it. nevertheless [the homepage] has been updated in a fashion that corroborates what you’re saying - as of the 20th of January, 2018, the first header reads ‘what was it?’ instead of the previous ‘what is it?’
though i was never subscribed, the digest was still a pretty big cornerstone of the internet otherkin community when i first stepped into it over ten years ago, and if you call yourself otherkin, you’ve got this list to thank. so to say it’s been important to the history of the alterhuman communities is a pretty big understatement.
thanks for bringing this to our attention, anon, so that we can give it the sending off it deserves.
