Revision assignments have been translated by human translators. You can recognise these assignments by the star-icon (figure 1)
Post-editing assigments have been translated by our translation engine. You can recognise these assigments by the monitor-icon (figure 2)
Because post-editing revisions may take more time than regular revision, the earnings for this type of translation are different.
