Discord is just a chat room. Though they like to cater to gamers.

If you look at the bottom left corner of the screen in-game, next to the options menu button is a text bubble icon. Click it and it opens a new tab/window for Discord, straight to the FKG channels. At least this works for me in the PC browser version of the game. Do note I already had Discord installed due to my MMO guild using it.

Is there any way to have multiple discord accounts? I've resisted using it for PPS and FKG due to being overload with different channels on my account. If I had 2 it would be much easier to keep track of it. (and avoid some awkward situations )
