and specify an expiration date for the announcement. You can include
links and mention users and groups in your announcement.
Group announcements display until 11:59 p.m. on the selected expiration date, unless they’re replaced by a new group announcement. Users can discuss, like, and post comments on announcements in the group feed. Group members receive an email notification when you post an announcement, same as for other posts, depending on their selected group email notification frequency. Deleting the feed post deletes the announcement.
