This tool would be another way in which you could communicate with your students in small groups, class size groups or for all of your different students. In our school we already have two different school maintained communication systems, one is Edmodo and the other is Managebac. Since these are accessible by the administration, it is best to stay with them. This removes any chances that there are issues with appropriate use. I could see that this might be very helpful for a teacher who working in a school where other school-wide programs are not available.
