If you click the Settings gear at the top of the Create Topic page, you can control the status of the topic (visible or not), start and end dates, and more. For accessibility standards, you should always keep Closed Captions active.
Important note: the end date refers to the very beginning of that day, aka midnight. For example, if we set our start and end dates to 05/20/2022-05/21/2022, students will only be able to post from 12:00AM-11:59PM on the 20th.
