VoiceThread Docs / Web Application / Commenting / Selecting the types of commenting available

Legacy VT

If you are the person who created a VoiceThread or you have editing rights for it, you can opt to disallow specific types of comments on that VoiceThread. You’ll make this selection in the thread settings

When anyone tries to comment on that VoiceThread, they will only see the commenting options you have allowed.  The rest will not appear as options at all.
