Next year we will have two projectors in our commons area which will play our daily announcements broadcast. With the announcements only being 5 minutes long I would like to have some form of informational slide-show on the screen the rest of the time reminding students of upcoming events, homework due, and other information. Thing is, I don't want to be the one in charge of putting all of this together and keeping it updated.
Question: What sort of collaborative program would anyone recommend that I could train teachers how to input information on and then with just a few clicks have it up scrolling/sliding on the screen after I finish broadcasting the announcements? Would google docs do this?
