I received an e-mail that mentions a 69 page document is SignWriting. At this moment a document in SignWriting is still considered to be exceptionally large. It does prove that people are able to write documents in their sign language that are this big. As more texts are written it will be not be special much longer.
The reason for me to mention it is that it indicates that SignWriting is stepping over a threshold. It is enabling American Sign Language to be a literary language. This is another step closer to the realisation of a Wikipedia for ASL.
