The group translation-manager-role contains all users that are allowed to start a translation workflow.

The name of this group has to be configured in the property translationManagerRole of the SiteModel (see Section “Site Model”). After changing this property, you have to upload the workflows again, because uploading persists the current property value.

The site manager groups define the users who may accept translation workflows for the content of a site.

Groups and Rights Administration for Localized Content Management describes how to set this property for every site.
