Within Teamwork, you can view the current spaces linked to your project.
While viewing the project, go to the Dashboard tab.
You will see a Project Spaces section at the bottom of the left pane.
Clicking the space name will open that space in a new browser tab.
Note: It is possible to link multiple spaces to a single project. However, an individual space can only be associated with one project at a time.
