I've been messaged by Lia Graf that Jeff Mancebo aka Boojum aka Golden Poppy passed away last Thurs after a months long struggle with heart failure. She has no other details at this time. He was an early member of this fandom, and his absence will be felt deeply.

If you know of anyone who would want to know this, please pass the news along.

UPDATE

Ghostchilde Miyelli (aurelioblackwind@gmail.com) has a memorial:
