Dear participants of the Bebras Intl. Task Workshop 2020, this mailing list (bebras-ibw2020@lists.bwinf.de) was set up to allow for more formal messages to you - while we had Zulip for many other purposes. Now, there is no longer a reason to keep this mailing list alive. It will be shut down within a few days. For mail-based communication of the Bebras community, we will keep using our traditional mailing list tasks@bebras.org (or: bebras-tasks@lists.bwinf.de). Anyone who is not yet subscribed to tasks@bebras.org but feels to be a permanent member of the Bebras community (in contrast to people who supported Bebras with a one-time engagement at the workshop this year) is asked to approach their national Bebras representative. These are always invited to get in touch with mail@bebras.org to ask for changes (additions or removals) to the tasks@bebras.org list. In the name of the Bebras Board, I say good-bye to all „one-time supporters“ at the Bebras workshop 2020, which was an extraordinary event in many respects. Thank you so much, it was great to be in touch and work with you.
