Because SetKeeper automatically saves drafts of your articles as you work, you can keep track of who made changes to the contents of an article as well as when the changes were made.

Click on More > History

You can see the name of the person who made the edits and the time the change was made in the column on the left. In the space on the right, you'll see the contents of the article as it appeared at that time and date.

To restore an older version, click on the date and time of the version you want to restore, then click on "Restore this Version".
