FWIW we use Zulip for scikit-image and we are very happy with it. See https://skimage.zulipchat.com . Advantages over Slack:

- free for FOSS, including unlimited archives (https://zulipchat.com/for/open-source/)
- login with GitHub
- Zulipchat is itself FOSS (I have successfully set up my own instance before)
- (upcoming) public archive (read without login)

I was trying to create a Slack workspace named numpy, but it turns out that
numpy.slack.com already exists. Does anyone have access to it or knows who
is administering it?

A lot of users try to grab all possible IDs available. A friend of mine
had reserved gmail-IDs of almost all celebrities, as if they will
register on Gmail. :-)

I guess, it is one of those. Try using some combination - 'numpy-xxxx'.
