I like that it allows for easy sharing between colleagues even if they're not close by at their desk or home (I use this feature often!). It also has an option so you can send out texts from your phone straight into the app instead of having to open up another program/app! There's nothing really negative about using this system but i wish there was more options when sending messages as well. If someone were waiting outside my office while we had time together i could easily have them message me through the application without needing to take the extra effort.
