How translations are selected

Members of the project are either a translator or proofreader. A translator can provide translations, while a proofreader can both provide translations as well as select the best translation to be used on the site.

The final translation that appears on our site is selected as follows:

  1. A proofreader selects the best translation.
  2. If there is no translation selected by a proofreader, translators vote on the best translation and the translation with the most votes is selected.
  3. if votes are tied, the most recent translation will be selected.
