Sometimes when you visit a website you would see that a chat window pops up. It would basically ask whether you need help with anything. Or it could be a means for requesting information. This adds value to a site. It enhances customer interaction. It is not too difficult to have this feature in your WordPress site or any custom site for that matter.
And once you are done with it you would get a new looking widget in your website with not too much effort 🙂
