No one seems to be at chatroom, and there is a lot of ads on the site

That's weird, there is always somebody at the chatroom. May be connection problems? We use websockets at chat and games, ports 8080, 2086 etc. Sometimes browser connects just after 5 seconds or so. If not, it prints to javascript console (f12 in Chrome) the error. It would be great if you could test it again. No need in registration, just visit any game,
this for example. I hope it will work.
