If the translation has NOT STARTED: 

Simply cancel the project (click “Cancel Project” on the project page) and create a new project with the full text for translation:

The credits from the canceled project will be applied towards the new project.  

If translation HAS STARTED or is READY: 

• Communicate the additional request to the translator via the Discussion Board. If the same translator is still available, he/she will translate the additional text for you.
• Using the 'Add Words' box on the project page, enter the number of words found in the additional text to reflect the translator's work. 
  
• If the same translator is not available, please submit a new project for the additional text only.
