For each segment, you can view who has made what modification at when.

To view revisions to a segment,

• Open the segment.
• Click Revisions tab.

If you cannot see the tab, that means the segment has not been translated and there are no revisions yet.

On the Revisions page, you can

• view the translation revision by clicking the date of revision.
• view the difference between the two revisions by choosing them and clicking Show diff button.
• revert the translation back to a revision by clicking Revert link.
