We have been bouncing from one live chat app to another because we can't settle on one that has all the features and functions the way we want it to. We used WHMCS Live Chat addon for a while, but recently changed to LiveZilla. Still not 100% on liking it.
Livezilla has a good chat function, the notifications, and desktop app. But the ticket functions are clunky, not very apparent, and we wish there was a way for clients to login and access old tickets.
Another odd thing about livezilla, their forums doesn't allow me to register! I'm using our domain email address, a different domain email address, gmail, hotmail, none of them work. It says that email address is not allowed at this community...?
