I recall some deaf chat rooms years ago. I think on chat frog or some name like that. I didn't participate much. Was a newbie to online then and wasn't comfortable chatting without face to face contact. Much better at it now.
Yeah back in the day, there was Deafchat that lasted for some time before it went down... memories. Then there's other Deaf chat and forums that didn't last long. Things change and people come and go. I have not been in any chat room in several years, I had a friend who regularly monitors IRC rooms back in the day but it has since died down as well.
