We just updated our forum software to Discourse 3.1 (thanks @izo !!). This is a major version bump that brings some new features:
One of the bigger ones is a live chat feature, which you can find via the speech bubble icon 
. We currently have just one room - let’s see how it works, try out the functionality, and then we can discuss what a useful setup would be.
Please feel free to use this thread to report issues you see with the 3.1 update, and new functionality you find that seems cool.
