This is an alphabetical list of the Language Brigade Wiki's chat moderators. In the chat, you can recognize them by the flag behind their name that indicates their native language or country. They may however be able to speak more than that language: feel free to check this out below, or on w:Template:WLB.
The chat moderators may be, but are not necessarily better than anyone else in a language. They are chosen to maintain the order in the chat room and to have users stick to the policy. Additionally, they will most likely know the WLB and its wiki better, and be able to point you in the right direction.
