Some of our instructors were confused by the similarities between the Announcement tool and the ability to message all students through Conversations/Inbox. The more I thought about it and tried to explain it, I realized that since there were so many overlapping features and some features unique to one or the other of these tools, I thought it might be helpful to make a chart that identified the features. Hopefully I got all of the features listed. If you see one that's missing, please let me know. Also, if you find any of the explanations confusing, or if I have not checked off a feature correctly let me know. And of course feel free to use this document with your instructors if you find it helpful.
