Responding to my own question. Apparently you can't. Yet the documentation says you can.
Note to Instructure: Can you please indicate in your documentation that a feature is not yet available? We turned it on globally yesterday and had to turn it back off today. Embarrasing
Hey there, @rgibson1 ...
That's a bummer. The best way to let the Documentation Team know that a Guide needs to be fixed is to scroll to the bottom of the document you linked in your question, and you'll see a link to "share your feedback". Using that link, the Documentation Team will get notified about your concerns, and they will review their documentation to make sure it is accurate.
I hope this will help a bit.
I've not found that to be entirely true here in the Community. In most cases, I've been able to edit my own replies here in the Community, but I wonder if that is a permissions setting because of my Coach status?
Hello @rgibson1 ...
Ah yes...thank you for the clarification. A couple days ago I responded to a similar question...which you can find at: Discussion, where is the edit function on Discussi... - Instructure Community. In summary, I am experiencing the same thing that you are with respect to the discussions redesign.
