This is from a post by Haru that I am placing here for everyone to be able to access.
ADDING for your easy viewing all the codes you can type in to use at the chat! Simply type the command and for some, replace what is in " " by your name/message. ALSO NOTE if it's a name change you can only input 1 name or phrase, no spaces (use underscore _ instead)!
User Commands:
/a "message" : Send Action Message
/clign : Clear Ignore List
/cls : Clear Screen
/create "room" "password" : Create Room (Password optional)
/help : Help & Command List
/ignore "username" : Ignore User
/info : Program/Version information
/join "room" "password" : Join Room
/listen "username" : Un-ignore User
/msg "username" "message" : Send Private Message
/nick "username" : Change username
/ping : Check server Ping response time
/whereis "username" : Locate user

Thanks Haru for posting this list!!!
