Changing name of Author

Hi, all of my FAQs have at the top ‘Written by’ and then the name of the author. I now need to change who wrote all my posts, but I can’t find the option any where.

In wordpress posts and pages we have the option to change the author on an individual post or via a Bulk action. Am I missing something? Or are you able to add this feature.

Brilliant plugin by the way.
