What are workspaces?

Workspaces are collections of lists, you can use them to seperate lists. Workspace are just like projects or folders. If you want to group some lists in a logical fashion, creating several workspaces is the way to go.

Example: If you want to plan your holiday with your family, you can create a new workspace and call it "Holidays". Then you create some lists for more detailed planing and invite your family to join in on the project.
