Use the Project - Roles preferences to add or delete the default roles for project teams and contacts.
Roles
Select a category from this drop-down list to add or delete default project contact or project team roles.
Project Contact Roles: Add the default project contact roles. These should be the common contact roles of others working on your projects (other than users) that you routinely use. Keep in mind that these are just defaults that are available for selection in the Projects-Contacts portal when a user goes to the Projects - General screen.
Project Team Roles: Add the default project team roles. These should be the common team roles that you routinely use for your projects. Keep in mind, these are just defaults that are available for selection in the Detail tab when a user is added to a project in the project's portal.
