When we were on Blackboard, I could not only delay an announcement, but I could also enter a close or hide date. I have several announcements that only need to be visible for a couple of weeks, but I don't delete them, because I need to make a quick update/edit & then repost them a year later. If I could enter an "end" date, I wouldn't have to remember to go back in 2 weeks & manually put in a "Delay Posting" date that is far into the future. Right now I have to do that just to hide them from my current students because they are no longer relevant to them, and relevant announcements can get lost in the shuffle.

Thanks!
