Here's what you forgot. If you're familiar with IRC (Internet relay chat) then you'll likely recognize the /me command. If you haven't ever chatted in an IRC Chatroom /me is kind of a way to speak in the third person. For instance, try "/me knows what your cards are.." (without the quotes) and your name will replace /me so if you're say, jaylord, you will say "jaylord knows what your cards are.." in the poker chat.

i also encountered a player who gave a tip to the dealer.. i'm wondering what coomand is that
it says '<name> gives the dealer a tip' or '<name> hands the dealer a tip' or something like that..

/bye is also the same as /cu

also, /grr only, not /grrrr
