one question to the CMK team: I am sure you already got the request to launch a Slack channel from somewhere else (if not - I do hereby ).
Is there already a decision for/against?
The Robot Framework team for example runs a Slack channel side by side of a discourse forum and it works pretty well. New forum threads are automatically announced by a bot in Slack to raise the attention of everybody.
I think it could be a great supplement, especially for tiny questions, relaxed chats etc…
(Just remembered that you ran a Slack channel for the CMK conference '20 - still alive…?)
