I looked a bit in the ggpk, and there seem to be some commands which are not shown in help, but still work:
/status <string> -> Sets your status
/accept <player> -> Accepts a friend request
/kick <player> -> Kicks a player from your party
/tradewith <player> -> Initiates trade with a player
/party_description <string> -> Sets the party description
/clear -> Clears the chat
/nochat -> Disables/Enables chat
/dnd or /donotdisturb -> Toggles "Do not disturb". I have no clue what that mode means. Maybe no tradings and pms or so
/squelch - /unsquelsh -> Same as /ignore and /unignore
Not Working:
/dance
/exit
Not sure If anyone ever needs this, but maybe it's useful :P
