2. Add other resources.

To import the existing team members from your organization, in Resource Sheet view, click on a cell in Resource Name column. A dropdown list will appear with resources that are part of your organization, but are not yet imported in your project.To add another resource that is not a team member yet, simply insert his name in Resource Name field. Later on, you can invite that specific resource into your organization by clicking on the Add Team Member button.
