FSFE's QuickML instance is currently not functional.
quickml is a service that allows quick ad-hoc mailing lists that everybody with an @fsfe.org email address can freely create on demand. Mails to that list are not archived, and the mailing list will destroy itself after a certain period of inactivity. The domain for these lists is q.fsfe.org.
Create a new mailing list
Just write an email to the new mailing list you want to create, and use your @fsfe.org email address as the sender. Place everybody you want to have included in the mailing list in Cc. The name of the mailing list is yours to choose. It should reflect the purpose of the mailing list and must end in @q.fsfe.org.
Subject: Planning for Foo-Meeting From: email@example.com To: firstname.lastname@example.org Cc: email@example.com, firstname.lastname@example.org Let's start with the preparations for this meeting!
You will receive an email asking you to confirm the creation of the new mailing list; just reply to this email and the mailing list is up and running!
From now on, you can just write to the list address (in our example email@example.com) to reach all the recipients on the mailing list.
Add a new member
Write an email to the list address and Cc the new member.
Subject: New volunteer From: firstname.lastname@example.org To: email@example.com Cc: firstname.lastname@example.org Hi, volunteer has just offered help with the preparations!
Everybody who is already on the mailing list may add new members this way.
Send an email to the list address and include any of the existing members.
Subject: I join you From: email@example.com To: firstname.lastname@example.org Cc: email@example.com Hello, I'm here to help you, too!
Send an email to the list address with an empty message body.
Remove a member
Send an email to the list address with an empty message body and put the address which should be removed in Cc.
The quickml software has a bug handling non-ASCII characters in the subject of the emails it distributes, but apart from that, it works just fine.
