cock.li has a rather active mailing list. you don't need an @cock.li email address to join, but keep in mind that the mailing list can get as much as 100 posts per hour. you'll want to set up a filter if you're going to use an email account you already use.
email firstname.lastname@example.org and respond to the confirmation email.
email email@example.com and respond to the confirmation email.
if you strictly use partial quoting (either remove the quote or only partially quote), then bottom posting is fine. otherwise, reply on top. don't reply on bottom if you're going to make people scroll past miles of quotes.
once you're subscribed, email firstname.lastname@example.org with your post. It will be copied to everyone in the list
