I don't know what is the process of this, but I would very much like to see Persian as one of the main forum languages. The thread in "Other languages" has more than 69,000 views: https://bitcointalksearch.org/topic/persian-620798
I know that theymos has consider adding local boards on this forum. It is just for the mean time that theymos has not yet provide the other local boards. As we all know that this forum continuously expanding in terms of numbers of people who join. Thus, we consider that this was one of the major contributing reason for high traffic posts on super mega threads.
Well probably this is already foreseen by the moderators of this forum.
Anyway, I wonder how much I could learn from them. I have tried already sneaking on some of the local boards and try to learn their language. The Nihongo is one of my favorite!
