The customer support team at OZNET were very helpful, both before we signed up for anything as well after it was installed in our system! They are always available to help out should any issues arise or questions be asked; they do so quickly too sometimes within minutes of my asking them.
Definitely recommend this software!! I've used other chat programs but not one that allows you all access from anywhere which makes things easier than having multiple logins/passwords etc.- just get your friends onboard using Group Chat if needed though because once logged into their own account some people can still see what others have said even when closed down by themselves (but don't worry about privacy concerns) - its awesome how easy communication becomes over group chats rather then through text messages only where everyone has time restraints like me haha:-).
