By default a new project is not shared with other workspace users. You can change the default behavior for a project in the New Project dialog box when creating the project or in the Edit Project dialog box. If the default role for a project is set to Contributor or Viewer new users added to a workspace are automatically given access to the project with the default role.
The Project Role for individual users can be changed in the Share Project dialog box.
Workspace Admins can view and modify all projects in the workspace regardless of their Project Role. Workspace Admins can change Project Roles for all users and projects from the Workspace Settings page.
