Have you created a course for this? How have you set this up?
We are giving the Canvas Admins area a little bit of love (especially questions that are really, really old) and just want to check in with you. This will also bring this question new attention.
Were you able to find an answer to your question? I am going to go ahead and mark this question as answered because there hasn't been any more activity in a while so I assume that you have the information that you need. If you still have a question about this or if you have information that you would like to share with the community, by all means, please do come back and leave a comment. Also, if this question has been answered by one of the previous replies, please feel free to mark that answer as correct.
Although we have an internal portal website (separate from Canvas) for both students and staff to use (where the majority of announcements are posted/housed), we do use Global Announcements (How do I create a global announcement in an account?) in Canvas on occasion to communicate things campus wide. We've worked with a couple departments on campus where they've sent us the information to post, and we'll post it for them for the amount of time they want. We try not to fill the Global Announcements up too much with content, however, because the more announcements you add, the more people have to scroll on the Dashboard.
