  1. I used the web interface link given above to subscribe to the mailing lists but I haven't got any approval emails yet. Should I be sending request to listname-join instead?

  2. We have seen on some occasions that subscribe verification notices end up either getting blocked by company level spam filters or end up in someone's junk folder,

    If you try using the LIST-NAME-join email and still do not get a reply, please send an email to  indicating the list you would like to join and noting that repeted attempts have failed and someone will add you by hand.

  3. It seems that there is no defined nor followed netiquette for ONAP mailing lists.

    I see that a lot of people respond using top-posting, html content, fancy html footers which are hard to strip from the message etc.

    html content and footers are really annoying for people (like me) who intentionally disable html content in their mail client.

    Additionally html footers which are not separated with a typical – are hard to strip out and they mix with email content.

    Above two together with common top-posting practice makes emails and especially mailing list archives very hard to read. I don't wanna to blame anyone so I don't provide any link to the archive but I recommend to just try to open any longer (above 10 messages) topic and then try to read, understand and guess who wrote which part of the email.

    That's why I would like to kindly suggest to define and follow ONAP mailing lists netiquette which follows good USENET practices described for example here.

    1. +1, I do echo your point. But I'm not sure this can/should be enforced. That said, it could be widly explain as common best practices.

      1. Well of course bottom posting is not sth you can easily enforce, you need to educate participants and remind them.

        But html stuff is sth that should be quite easy to do. I saw a lot of mailing lists which siply rejects the message if it's not a plain text. I expect that ONAP lists could be also configured in that way
