I do not know whether Xal0lex can speak Urdu (assuming it is the local language used) or not, but if there is no local mod who can evaluate the quality of posts and the extent of off-topic, it is better to be Bitcoin only discussions, with off-topic thread.
I am pretty sure one does not need to be a local language speaking or writer these days to moderate a local board. Google translation does the basic duty however for quality moderation, a local board needs a local language speaker.
All Local boards - Discussion of various topics in the appropriate language. Posting translated coin announcements is limited to languages that have their own section (a.k.a. dedicated board with sub-boards)
Not the sub-board.
Xal0lex also pointed out that a rule from hilariousandco states that only bitcoin related posts are allowed in local languages section.
mprep talked about sub-boards but hilariousandco did not mention anything about it. It could be a misunderstanding and the result is the deleted posts where there is only one topic for the local community.
