How to change a Project Manager for a project

How to assign your translation project to a different project manager

To change a project manager in the ongoing translation project, open the project details page, by clicking the project's name.

Click Edit icon next to the Project Manager and select a user from the list. 

You may only assign a project to a Power User or to Text United translation services (Paid service)

You can add new users or upgrade existing ones in the TEAM page.
