Navigate to the project's Info tab, and then to the Members section to view the list of current project members. Below their names will be their organization and their project role.
Project owners, designated with the symbol, can view and edit members' permissions by clicking on the user's menu button and choosing Edit Permissions. Other members will not have permission to do this. Permissions will set a user's view, edit, and delete privileges for project settings, time entry, organizations, users, requirements, tasks, bugs, test coverage, and documents.
By default, project owners have access to all the project tabs. Project ownership is reserved for users of internal organizations.
