The server is made up of players from almost every region, so groups mostly keep to themselves. Most people are also waiting for the source update, but we have had delays as we are having to re-design large aspects of the game (we're currently finishing up a new file/package system which has been why there has been a lull in news).
The Discord is mostly only active when I am actively talking, or when news has posted or when someone needs support.
Honestly, it's about as active as you can expect of a badly designed game from 2013 that is undergoing re-development.
