The Closed-Captioning permission is not included in the default set of Global permissions - not even for Moderators (including yourself). Before Moderators and Participants can enter text in the Closed-Captioning input window, you must explicitly grant them the Closed-Captioning permission.
Moderators and Participants do not need the Closed-Captioning permission to read another person's Closed-Captioning text.
To grant the Closed-Captioning permission to an individual Moderator or Participant, select the Closed-Captioning permission in their Participant Options menu.
When users are granted the Closed-Captioning permission, they will see the Closed-Captioning button added to the title bar of their Audio & Video panels. This is the button they will use to open the Closed-Captioning window to enter caption text.
