Hi Gerard, Please read further down the thread, you will see that Mark addressed this issue already. There is a sizeable number of people in favour of signed Wikipedias; what remains to be seen is *how* it will be done.
I also addressed the issue of how it should be done. In short, my proposal was advocation of using sign synthesis software, the likes of which already exists.
Yet again I am forced to ask: Is there any existing literature in sign language?)
In American Signed Language, yes. That's if you define "literature" as written only. I personally would include the signed version of "oral literature" (perhaps "manual literature"?), because much more of that exists. However, there is printed literature in ASL. The writing systems used vary widely.
Oh, and if all these people for whom sign language is their primary language have only a 4th-grade reading level, how are they supposed to even get on the internet and contribute to a signed Wikipedia? The last time I checked, teaching literacy was *not* a primary goal of the Wikimedia Foundation.
Most people with 4th grade reading levels should be able to connect to the internet.
Mark
