Like the other reviewer on here, I was looking for a module that would enable IM capability between a user on the website and end user who would be online. The context is for a campground that I'm setting up a website for. They needed to be able to talk to people in realtime via a chat tool. There are surprisingly few items in Joomla that will let you do that. Most of them didn't work because they were designed for people to chat as a group online OR they didn't have a way to let you know someone was trying to contact you. This tool has a nifty (and very light) client application you can download to intercept any messages. I changed the WAV file to the standard Yahoo one, because it is much more audible to someone sitting around a terminal. Works like a champ. The only downside is that you have to use the embedded Flash object that Chatango references you to. And you are stuck with the "Get Chatango" link and a link that asks users to get a Chatango Account if they don't want to be anonymous.

But hey!!! Easy to install and set up. I had chat running inside of 5 minutes.
