If you are having issues with the evaluation interface and yellow and grey markers, please see this article.
If you are concerned that there is no written feedback, please see this article.
Due to the large size of each community at Unbabel, it’s unfortunately not feasible to provide a detailed critique of every task that is sent to evaluation. This does sometimes mean that evaluations are not as clear as they should be to all editors.
Evaluation results should provide: (a) a general comment about the quality of the translation produced and (b) a list of errors and suggestions for improvements (if any). Take care to go through this list and trace the mistakes, then go through the language guidelines.
