I have checked several options to send out site-wide announcements for our school, but cannot seem to find the right block or plugin to pull it off. All I need is a block in the top center of every user's home page that displays news and announcements. I need control of users and the ability to lock it in place so no students accidentally hide it. It would be nice if it were a news block so we could have dates and times of posting listed as well.
If anyone has a suggestion, let me know!
