There is one in Australia but their opening page is messed up; says to register but ya can't. Glitch and if they are wondering why nobody new is coming, that's it...hopefully, they will see this and fix it.
Dixie, I do run a deaf forum for Australia, but otherwise, no there is no deaf chat on the forum as I am not permitting these sort of chatrooms. Sorry. Also Tousi, which deafchat are you referring to for Australia residents?
