I like how it can be used to communicate between us, teachers, parents and other people involved (e.g., relatives). It's also great because you don't have to get your phone out every time when there are changes happening during school hours. Nothing so far! The best thing about this program is its convenience; we use it as much or even more than our phones do currently. We've been able to keep up communication using it at all times without having to constantly check if they're available online/on their apps anymore.
