Discord is a voice application that allows you to voice and text chat with users from all over the Hypixel Server.
What is Discord?
Discord is a computer and mobile software that allows users to voice chat with others in their channel, much like a telephone conference call. The Hypixel Discord has text channels linked to the voice channels so that users can type as well as voice chat. You can see here on how to join the Official Hypixel Discord.
