Discourse is Looker’s community forum. It’s a great place to discover use cases, discuss best practices, troubleshoot unique issues, and communicate with other Looker customers.
Learn is Looker’s sandbox environment, primarily for developers. It includes lessons linked to real datasets in a real Looker instance, so you can understand the impact of developer changes.
If you’re still stuck, try reaching out to our Department of Customer Love with your Looker’s chat functionality, or email firstname.lastname@example.org.
