First, Welcome to the Dope! I hope you stay!
I have always been fascinated by sign language and deafness. I have a cousin that has extremely limited hearing and uses hearing aids and lip reading which fueled my interest early on.
In high school I made a friend with the only deaf girl in our school and really enjoyed learning signing. At one point I thought of doing it for a living. But, focusing on one thing has never been my speciality. Lack of focus seems to be a Doper Strong Point. 
I’ve always kept my basic alphabet knowledge fresh. ( I even came out of sedation once from having my teeth pulled and I was doing my sign language…heh.)
My hobby is writing, and I decided a few years ago (during the Sydney Olympics…whenever that was…94? 96? 98?) to write about a single mom who had a daughter that was deaf… never finished the story…got sidetracked by other…things…focus?moi?..and the ironies of ironies is last summer this happened to me for reasons that will never be understood and probably I will suffer from the vertigo again and have more hearing loss as I age.YAY!
I have 55% hearing loss in my right ear and ( this is the worst part) tinitus. Nonstop.
As long as it is not a precursor to something wicked and nasty, I’m completely fine with everything. (Yeah, it is a pain to locate noise now, espcially the telephone or cell phone. Taking all noise info in one ear is a audiotory swim.)
The specialist I went to recommended the Baha System which I know of no one who has had this done. It is relatively new. Do you know of anyone who has had this implant done?
My other questions for you are:
Are there any childrens/chapter books out there that tell the story of these two gentlemen who started it all? I’ve never found one on my own. For blindness and leader dog/braille, yes. But I haven’t seen anything for the start of sign language.
I am trying to expose my children to all areas of disability in a humane fashion. We have, in both sides of our family severe physical disabilites, so they are on the ahead of the game there from most kids their age.
And two, is there a different kind of sign language for english speaking countries; ie, do Aussies sign a little different or mostly different? Is it called the same thing?
Three, and it just popped into my head so forgive me if it is jumbled, the chinese alphabet is what, 3000 characters or so…how do they figure out how to sign it all?
Fourthly, since you are deaf, and a guy…you must be pretty good with your hands she says knowingly. 
Fiftly, do you have balance issues?
I’ll shut up now.
