Great responses! Seems like the only special procedures to accommodate, is to merely use common sense.
That's my plan too.
I have a deaf guy in my poker league. Great guy. Understands the game very well, and generally follows the action and knows the blind levels better than other players.
The only thing I have done special for him is, if a player bets or calls using an oversize chip, I'll be diligent about breaking the chip down so the chips in front of that player is the correct bet, making it easy for the deaf guy to see how much was bet, without asking. It has since become a habit for me. I'll break down those oversize bets, even if that deaf player isn't even playing that night! Turns out that doing that makes things easier for novice players too.
