AFK Settings in Discord
If your server doesn’t have an AFK channel, you won’t be kicked from a voice channel for inactivity! After a user has been inactive for around 5 minutes, Discord will automatically set the user’s status to Idle. Users can set this to let others know if they are available or not.
Using Dyno for AFK Status
Dyno will automatically add "[AFK]" to the beginning of your nickname whenever you set an AFK status (if it has the permissions to). To remove your AFK status, simply talk in any channel which isn’t ignored and Dyno will remove your status.
