Every now and then you have a project that you aren't working on anymore, but don't feel like deleting just yet. You want a result similar to deleting a project, but without actually deleting it and losing all its data.
For such cases, you have the option to archive a project.
To archive a project:
Click the Projects link in the header to open the Projects list.
Open the project settings page of a project that you want to archive. You can do this in two ways:
From the Projects list, open the context menu and select Settings.
Open the project overview page and click the Settings link in the Administration section of the sidebar.
