You can sign up at https://python.zulipchat.com/register/ . Do read the text on the sign-up page as it mentions key things like automatically hyperlinking for issues, the CoC, etc. The instance is currently very open at Zulip's/Greg's suggestion. That means people can add bots, create streams, etc. If this starts to get out of hand we can lock it down and make those things admin-only. Otherwise we are leaving it open for now to see what practices emerge from usage. To start, I have created several streams that orient around various mailing lists we already have. I also set up bots for commits, PR comments/reviews (although that's so new I have not seen it triggered yet :), and bot deployments for Bedevere and the Knights Who Say Ni (when Mariatta comes back from her break we can ask her to hook up miss-islington). I think this covers the major areas of our workflow to get us started with this experiment. Initially this should be oriented towards the development of Python and not using Python. If this experiment turns out really well we can talk about either expanding this instance or opening a separate instance for people to go discuss Python in general, using it, getting help, etc. I am also not announcing this on python-committers or python-dev yet until we have played with it for a week or so. If this ends up looking like a worth-while experiment and experience then we can make a broader announcement. And then after that if this continues to be beneficial we can then start discussing officially integrating Zulip into our communication ecosystem for core development.
