The ability for our office staff members of different departments within my organization to communicate with each other easily without having everyone at an individual desk or computer is great! I have yet to run into anything that has been negative about this software so far but if you are looking out there then it may not be good enough however since we currently use P2O no one else can complain either because they do all their work through them too!! Overall its very easy user friendly system which makes communication between offices easier than ever before.
