I've recently gotten an EIR discord server up and running in an attempt to acquire the millennial/hipster demographics. That being said, I would recommend that everyone join. It allows for easily setting up games as it has a global chat function that the EIR steam group does not have. You can also get live bug/query help as well as see live patch progress notes. Most importantly it can double as voice comms for your matches. You can access it either through your web browser or by downloading the application.
Invite link is as follows:
