I am a freelance writer, and for any potential clients, I have installed a chatroll widget on my blog, so that they can contact me for any requirement of theirs. It is a breeze to install, and I can see if anyone comes online and chat with them. But I am also missing on the visitors whenever I am not online. Is there a client side live chat solution that sends you an email when you are away, or even when you are online ( but are busy somewhere else)?
