You can manage the project participants in the Translators tab on the Project Settings page. Project managers, translators and proofreaders can be a part of your team.
If an option Limited Access to the Languages is enabled, you can invite translators or proofreaders to the specific languages. See Advanced Project Setup for more information.
There are three main methods of involving participants to the project with the Invite People button. In each case, select a role and a language (limited language access policy).
Also, you can cooperate with professional translation agencies. For this, click the Vendors Marketplace button or go to the Vendors tab.
