We had in the past the issue that people would get muted, but never unmuted. I have now programmed our own interface for this and now it is impossible to mute someone accidentally forever.
The default mute is for 1 hour, and I would recommend to keep it for one hour. If someone gives another reason to be muted right after the mute expires, I would recommend a ban instead of another mute.
The new commands are visible for Masters and above in the /helpme in-game help, under a new section of commands “/mod“:
/mod mute <player> [time]
/mod unmute <player>
