Better than this is used by https://noobs.group webmaster.

I have created the similar thing. But with real chat. I do not have to add chat layouts for two parties.

It automatically happens when anybody reply to topic created by other user.

Have a look on below chat post, or try to make your own topic or reply to any topic that is there on site.

And you will see chat layout is automatically created:

Its advanced version of live chat by using the core features of WordPress. No special setup needed.

It’s no doubt that conversional blog or chatting blog is the future blogging.
