The problem with that is that not all builders are on forums. In fact, the few I do see here on forums arent really even that active here. The reason there is a tag for the build team leader is so that people know who is the one who can actually accept or decline a map, or who to contact with questions about applying for buildteam. Just as there is no reason for there to be a command to list online builders, I see no reason to have them ranked on here as there reallt wouldnt be anything special about the rank.
