How to setup chat for live support

Hi,

I am little unhappy with this plugin. I want to allow random users that have not signed up to my WP site to be able to chat to my support team at any point. Currently from the options I can see the visitor has to be registered, and therefore that stops most visitors from chatting to our support staff.

So is there a method to allow visitors to chat to our support staff just like most other live support plugins.

Thanks
