djangocon eu slack and contact information

[Jason Johns]

At the django-users google group, someone made a recent post https://groups.google.com/g/django-users/c/E4SX505gTCY about the djangocon EU announcement.  Looks like there's two references to the conference Slack, one of which is

> We hope we'll see you all at DjangoCon Europe 2022, and don't forget to follow us @djangoconeurope on Twitter, and also join our dedicated Slack channel.

That Slack link goes to a sign in page, there's no means to do a sign-up if you don't already have an account at that workspace.  I don't have a twitter account and there's no , so was curious if there were a means for anyone here to pass this on to David or Miguel at djangocon EU?  I tried sending a message to con...@djangocon.eu, but that address was not found.
