Does anybody have discord and what is it ?

No and  discord is a proprietary freeware instant messaging and VoIP application and digital distribution platform designed for creating communities ranging from gamers to education and businesses

Video games and the internet go together like Doritos and Mountain Dew. With the internet, you don’t need to seek the bustling crowds of an arcade or wrangle friends together for gaming on the couch. They can enjoy cooperating with or competing against other people all over the world. Granted, online multiplayer isn’t always a pleasant experience, especially when it comes to communication. Listening to random faraway strangers curse at you can be enough to make you want to burn your headset. However, experiences such as conducting epic MMO raids or coordinating tactics with your teammates in shooters just weren’t possible in the era before online chat
