It will be hard for global mods and other moderators to handle local reports. You may not understand what are they talking about due to the language barrier. We cannot rely on google translator. FYI, I have applied to be a Local moderator but I didn't get any response yet. I guess it is the president and Vice president who hire moderators. I didn't get any positive or negative feedback about my application. But I would be glad to work if you guys need a guy from my locals. About development works, I do not want to send Private messages and bother them. Since they have the priority list, they will have to follow them for sure. We should be more patient instead.
It's true that language is a big barrier, but with the help of the local user reporting it it shouldn't be a serious problem, but that's just my opinion.
Regarding your application to be a local moderator, I can tell you that it is not something that can be done in a few days or weeks. What @hair and I do is monitor the users who have applied for that position and in a few months we can decide who will fill that position.
We take into account the activity of these users, the quality of their posts, the way they talk to others, and overall we will be able to verify that the user will do a good job.
Even if you haven't received any notification or response, don't worry, we take all requests into account.
