We've set up an IRC server for our site. For those that do not know what IRC is, it's a system used for internet chatrooms, and has existed for more than 20 years already 

It should still be considered experimental. We're not sure if we'll keep our own server, create a channel on a public, free IRC network, or even close down the chat again. It depends on how popular the service is, and how much it gets abused.

For now, you're all invited on our official IRC channel 
The details are here.
