+==============================================================================
+
+1. About the lists
+
+  1.1 Mailing Lists
+
+  The mailing lists we have are all listed and described at
+  https://curl.se/mail/
+
+  Each mailing list is targeted to a specific set of users and subjects,
+  please use the one or the ones that suit you the most.
+
+  Each mailing list has hundreds up to thousands of readers, meaning that each
+  mail sent will be received and read by a large number of people. People
+  from various cultures, regions, religions and continents.
+
+  1.2 Netiquette
+
+  Netiquette is a common term for how to behave on the Internet. Of course, in
+  each particular group and subculture there will be differences in what is
+  acceptable and what is considered good manners.
+
+  This document outlines what we in the curl project consider to be good
+  etiquette, and primarily this focus on how to behave on and how to use our
+  mailing lists.
+
+  1.3 Do Not Mail a Single Individual
+
+  Many people send one question to one person. One person gets many mails, and
+  there is only one person who can give you a reply. The question may be
+  something that other people would also like to ask. These other people have
+  no way to read the reply, but to ask the one person the question. The one
+  person consequently gets overloaded with mail.
+
+  If you really want to contact an individual and perhaps pay for his or her
+  services, by all means go ahead, but if it's just another curl question,
+  take it to a suitable list instead.
+
+  1.4 Subscription Required
+
+  All curl mailing lists require that you are subscribed to allow a mail to go
+  through to all the subscribers.
+
+  If you post without being subscribed (or from a different mail address than
+  the one you are subscribed with), your mail will simply be silently
+  discarded. You have to subscribe first, then post.
+
+  The reason for this unfortunate and strict subscription policy is of course
+  to stop spam from pestering the lists.
+
+  1.5 Moderation of new posters
+
+  Several of the curl mailing lists automatically make all posts from new
+  subscribers be moderated. This means that after you have subscribed and
+  sent your first mail to a list, that mail will not be let through to the
+  list until a mailing list administrator has verified that it is OK and
+  permits it to get posted.
+
+  Once a first post has been made that proves the sender is actually talking
+  about curl-related subjects, the moderation "flag" will be switched off and
+  future posts will go through without being moderated.
+
+  The reason for this moderation policy is that we do suffer from spammers who
+  actually subscribe and send spam to our lists.
+
+  1.6 Handling trolls and spam
+
+  Despite our good intentions and hard work to keep spam off the lists and to
+  maintain a friendly and positive atmosphere, there will be times when spam
+  and or trolls get through.
+
+  Troll - "someone who posts inflammatory, extraneous, or off-topic messages
+  in an online community"
+
+  Spam - "use of electronic messaging systems to send unsolicited bulk
+  messages"
+
+  No matter what, we NEVER EVER respond to trolls or spammers on the list. If
+  you believe the list admin should do something in particular, contact them
+  off-list. The subject will be taken care of as much as possible to prevent
+  repeated offenses, but responding on the list to such messages never leads to
+  anything good and only puts the light even more on the offender: which was
+  the entire purpose of it getting sent to the list in the first place.
+
+  Do not feed the trolls.
+
+  1.7 How to unsubscribe
+
+  You can unsubscribe the same way you subscribed in the first place. You go
+  to the page for the particular mailing list you are subscribed to and you enter
+  your email address and password and press the unsubscribe button.
+
+  Also, the instructions to unsubscribe are included in the headers of every
+  mail that is sent out to all curl related mailing lists and there's a footer
+  in each mail that links to the "admin" page on which you can unsubscribe and
+  change other options.
+
+  You NEVER EVER email the mailing list requesting someone else to take you off
+  the list.
+
+  1.8 I posted, now what?
+
+  If you are not subscribed with the same email address that you used to send
+  the email, your post will just be silently discarded.
+
+  If you posted for the first time to the mailing list, you first need to wait
+  for an administrator to allow your email to go through (moderated). This
+  normally happens quickly but in case we are asleep, you may have to wait a
+  few hours.
+
+  Once your email goes through it is sent out to several hundred or even
+  thousands of recipients. Your email may cover an area that not that many
+  people know about or are interested in. Or possibly the person who knows
+  about it is on vacation or under a heavy work load right now. You may have
+  to wait for a response and you should not expect to get a response at all.
+  Ideally, you get an answer within a couple of days.
+
+  You do yourself and all of us a service when you include as many details as
+  possible already in your first email. Mention your operating system and
+  environment. Tell us which curl version you are using and tell us what you
+  did, what happened and what you expected would happen. Preferably, show us
+  what you did with details enough to allow others to help point out the
+  problem or repeat the steps in their locations.
+
+  Failing to include details will only delay responses and make people respond
+  and ask for more details and you will have to send a follow-up email that
+  includes them.
+
+  Expect the responses to primarily help YOU debug the issue, or ask YOU
+  questions that can lead you or others towards a solution or explanation to
+  whatever you experience.
+
+  If you are a repeat offender to the guidelines outlined in this document,
+  chances are that people will ignore you at will and your chances to get
+  responses in the future will greatly diminish.
+
+  1.9 Your emails are public
+
+  Your email, its contents and all its headers and the details in those
+  headers will be received by every subscriber of the mailing list that you
+  send your email to.
+
+  Your email as sent to a curl mailing list will end up in mail archives, on
+  the curl website and elsewhere, for others to see and read. Today and in
+  the future. In addition to the archives, the mail is sent out to thousands
+  of individuals. There is no way to undo a sent email.
+
+  When sending emails to a curl mailing list, do not include sensitive
+  information such as user names and passwords; use fake ones, temporary ones
+  or just remove them completely from the mail. Note that this includes base64
+  encoded HTTP Basic auth headers.
+
+  This public nature of the curl mailing lists makes automatically inserted mail
+  footers about mails being "private" or "only meant for the recipient" or
+  similar even more silly than usual. Because they are absolutely not private
+  when sent to a public mailing list.
+
+
+2. Sending mail
+
+  2.1 Reply or New Mail
+
+  Please do not reply to an existing message as a short-cut to post a message
+  to the lists.
+
+  Many mail programs and web archivers use information within mails to keep
+  them together as "threads", as collections of posts that discuss a certain
+  subject. If you do not intend to reply on the same or similar subject, do not
+  just hit reply on an existing mail and change the subject, create a new mail.
+
+  2.2 Reply to the List
+
+  When replying to a message from the list, make sure that you do "group
+  reply" or "reply to all", and not just reply to the author of the single
+  mail you reply to.
+
+  We are actively discouraging replying back to the single person by setting
+  the Reply-To: field in outgoing mails back to the mailing list address,
+  making it harder for people to mail the author directly, if only by mistake.
+
+  2.3 Use a Sensible Subject
+
+  Please use a subject of the mail that makes sense and that is related to the
+  contents of your mail. It makes it a lot easier to find your mail afterwards
+  and it makes it easier to track mail threads and topics.
+
+  2.4 Do Not Top-Post
+
+  If you reply to a message, do not use top-posting. Top-posting is when you
+  write the new text at the top of a mail and you insert the previous quoted
+  mail conversation below. It forces users to read the mail in a backwards
+  order to properly understand it.
+
+  This is why top posting is so bad (in top posting order):
+
+      A: Because it messes up the order in which people normally read text.
+      Q: Why is top-posting such a bad thing?
+      A: Top-posting.
+      Q: What is the most annoying thing in email?
+
+  Apart from the screwed up read order (especially when mixed together in a
+  thread when someone responds using the mandated bottom-posting style), it
+  also makes it impossible to quote only parts of the original mail.
+
+  When you reply to a mail. You let the mail client insert the previous mail
+  quoted. Then you put the cursor on the first line of the mail and you move
+  down through the mail, deleting all parts of the quotes that do not add
+  context for your comments. When you want to add a comment you do so, inline,
+  right after the quotes that relate to your comment. Then you continue
+  downwards again.
+
+  When most of the quotes have been removed and you have added your own words,
+  you are done.
+
+  2.5 HTML is not for mails
+
+  Please switch off those HTML encoded messages. You can mail all those funny
+  mails to your friends. We speak plain text mails.
+
+  2.6 Quoting
+
+  Quote as little as possible. Just enough to provide the context you cannot
+  leave out. A lengthy description can be found here:
+
+      https://www.netmeister.org/news/learn2quote.html
+
+  2.7 Digest
+
+  We allow subscribers to subscribe to the "digest" version of the mailing
+  lists. A digest is a collection of mails lumped together in one single mail.
+
+  Should you decide to reply to a mail sent out as a digest, there are two
+  things you MUST consider if you really really cannot subscribe normally
+  instead:
+
+  Cut off all mails and chatter that is not related to the mail you want to
+  reply to.
+
+  Change the subject name to something sensible and related to the subject,
+  preferably even the actual subject of the single mail you wanted to reply to
+
+  2.8 Please Tell Us How You Solved The Problem
+
+  Many people mail questions to the list, people spend some of their time and
+  make an effort in providing good answers to these questions.
+
+  If you are the one who asks, please consider responding once more in case
+  one of the hints was what solved your problems. The guys who write answers
+  feel good to know that they provided a good answer and that you fixed the
+  problem. Far too often, the person who asked the question is never heard from
+  again, and we never get to know if they are gone because the problem was
+  solved or perhaps because the problem was unsolvable.
+
+  Getting the solution posted also helps other users that experience the same
+  problem(s). They get to see (possibly in the web archives) that the
+  suggested fixes actually have helped at least one person.
