Welcome. Can you by any chance post some detailed information of Saudi Arabian sign language/languages that are currently used in Saudi-Arabia? I have seen Jordanian sign language by a random encounter in Dublin Ireland of all places (great town, alas thats another story), and know of its use in al jazeera broadcasting for interpreting the Arabic of the broadcasts. I have also seen via youtube Saudi sign language, But there is very little written information that i have come across dealing with it and/or its characteristics.
Are you familiar with the the Cambridge language surveys-sign languages. section 3: variance and change, chapter 19 sign languages in the Arab world? i found it lacking.
