[mch2022-orga] Mailing lists & Sunsetting MCH2022 Support ticket system

[Xesxen]

Hi all,

WHY2025 mailing lists (on lists.why2025.org) were broken for the last
two weeks. This has been rectified and won't happen again in this
manner.

We've moved all active mailing lists over to lists.why2025.org. You can
see the current list of lists on https://lists.why2025.org/. The old
mailing list addresses (@lists.mch2022.org, or even mch2021 for some of
them) will remain working to ensure you won't be missing emails on any
of the lists. If you want your old list to be moved over or want a new
list to be created: reach out to us via sysadmin at why2025.org.

Lastly: As mentioned in today's orga meet we're planning on sunsetting
the MCH2022 support system (support.mch2022.org) by the end of the
month. If your team has used this before and want to retain access to
the same mail address (for eg. accounts on external systems) or are
unsure if your team has used it before: reach out and we'll help you
out.
