How do I create a "Master Project"?

The "Master Projects" feature is deprecated, and has been replaced by the "Spaces" feature.

To create a new "Master Project":

• Login using an account that has 'Administrator' privileges.
• Click Settings on the top-right, and select Manage Users from the menu.
• In the resulting page, click Create "Master Project" link under "Manage User Roles" section.
• In the page appears, define criteria for this Master Project. Then click "Save" button.

Once you create a master project - you can assign it to a custom user role as explained here.
