I will help a lot to have an Moderator for each language, support will be more easy to offer, yes is a problem because not every person want to help is for trust but every persone need a chanche to prove what they can do, i am from Romania for example and i see no forum for our contry, you can try to make some test period for the persone who want to help something like „Junior Moderator” and if its good to become Moderator.
