There are a few configurable options for LushBots AFK settings, You can view its settings by typing:
Should you type while AFK is enabled LushBot will automatically disable your AFK status, soon this will be an option.
By default your AFK message is set to: > your name here < Is currently AFK!
!afk message (type your own reply)
When setting your custom message you are not aloud to mention other members and if a server admin decides its unsuitable they have the ability to reset it.
