Some updates and one thing for fun:

• Changed global background to a little bit lighter
• Changed search to "like". Regarding performance it's going to be slow if you will have thousands of chats. So i suggest use archive module and search only then you need.
• Updated translations - full Russian translation.
• Fixed bug then sound was not always played, now I just use autoplay.
• Chat widget window is a little bit cleaner now. Less borders, more space.

And one extra image for fun. Now you see how fully automated invitation and responses is doing it's amazing job. :)

And I remind one more time. There is no real person behind demo.
