https://www.haiku-os.org/community/ml/etiquette says to send an email to <haiku-request@xxxxxxxxxxxxx> with *subject line* "unsubscribe" or https://www.haiku-os.org/community/ml/ has other instructions I do believe this is the "Haiku General Mailing List" - go through the process of subscribing, but when you are typing your email select "unsubscribe" in the dropdown menu instead I'm sorry to see you're leaving us :( -Taylor
