The community manager has gotten back to me privately and said they see no need for a slack channel since the community forums are sufficient. I have therefore started my own "databricks-clients" slack workspace.

Please click this link to join it (note, this link expires after 30 days).

You should also be able to join by going to this link: https://databricks-clients.slack.com

And please spread the word. The dream would be to fill this workspace with thousands of Databricks users, and where we can share ideas / seek support / showcase our business use-cases.
