Overview
Mark yourself away with an optional reason. Anyone who mentions you while you’re AFK gets told you’re away, and it clears automatically the moment you send a message again. Use it before you sleep, go to work or leave for a few days, so nobody waits for an answer. When you come back,!afk mentions shows what you missed.

In Discord: a member goes AFK, and Petto answers whoever mentions them.

In Discord: the AFK member writes again, the status ends and Petto says how many mentions are waiting.
Commands
