Yes!  And it's very simple to do.

1. Navigate to the "Live Content" tab in the Q&A section of the Portal.

Here, select the question(s) that you would like to edit or delete by checking the box to the left of those corresponding questions.

2. Once you have the question(s) that you want to edit or delete selected, click "Unpublish Selected QnA & Send Back to Edit"

3. The above process will move those questions back to the "Compose QnA" tab.  Here you can edit or delete those questions.

4. Lastly, once your edits are made, just remember to move the edited questions back to "Review" and then to "Live Content" because only the content in the "Live Content" tab is what is live to your customers.  Once the content is back in "Live Content" it is immediately live on any channels you have activated in Zammo.
