Technically there is no reason to why not having a section for Arabic speaking language.
They may not know that there is 500+ million Arabs out there which is something not to ignore.
I advice you my mate to add a poll to your thread & see how many Arabs overall in BCT. they'll be shocked for sure.
Thank you @ansi for kind words actually numbers of Arabic readers at bitcointalk increased since that time (July 16) when this request raised to bitcointalk management and still we are waiting for Arabic section even for temporary period of time to test how active we are . if you look at other language you may found lots of new translation\questions asked daily in Arabic from new comers and deleted by MODS.Hope admin of bitcointalk help us to create special section for Arabic speakers before end of 2017 . also i will update the OP with adding voting poll as suggested .
Thank you again and many thanks to bitcointalk administration .
