How do I request revisions from a writer?

FAQ - Revising Pieces

An assignment’s status will change to Pending Review when it is completed by a writer. 

To begin editing, click the Start Editing button located in the bottom right-hand corner of the assignment window. A toolbar will appear at the top of the assignment and will provide the Producer with everything needed to edit the piece and provide feedback.

Most notably, there is a comment bubble on the toolbar.  You can highlight words, phrases, sections of text, whatever you need.  Then, click on the comment button and leave the writer your notes for what to change.  Hit Enter, and the comment will save.

Once the Producer has completed their edits they can then select Send back for edits.
