When we want information posted to the website to “disappear” at a certain time, we can use the Post Expiration feature.
This feature will allow you to create a post on your homepage or in your events area that will take itself off of the website at the specified. This feature is useful for time-sensitive alerts and information that doesn’t need to be accessible after a certain time.
