This chat program does exactly what we need. I have tried several different programs, and this is by far one of the best for our purposes with the features we need and a great price. It was simple to set up and is easy for users to understand. It also works very well on various platforms, including phones, which is a must in our busy mobile environment.
Support is excellent and fast. The developer is very nice and great to work with. We have a complex site with a lot of extensions, and the developer was very patient in helping us figure out a couple of issues that had occurred. That being said, it was all resolved rather quickly and efficiently.
