Can you invite me to join the slot channel?
You don’t need invitation. You can find the correct Slack link on the Docker Support page:
I leave the direct link here, but it can change in the future: http://dockr.ly/comm-slack
Something has changed recently. I’ve been a member of the Docker Community Slack for quite a while. But Slack dropped my connection sometime in the last week. If I try to rejoin, I end up at a page that says I need an @docker.com email:
I managed to re-join by deleting the old Slack from my desktop app and signing in again via https://dockercommunity.slack.com/ , so I’m good to go. But others might have run into this same issue.
