Basically, there was a time when there was a very distinct division ebtween those who looked after forums and those who had responsbility ofr the whole site and had powers over ALL the forums, and comprise the Jedi Council for the site with their own area of the for,ms which people suspect is some secret funhouse but is actually the same as everywhere else, including queeq getting things off-topic ASAP.. There is nothing to stop the second being the first as well- i.e. you can be a mod for the whole site but still more specifically expected to particularly look after one area as well.
Various changes means that Mah is currently the only person who runs a forum but it not a mod. All the other forum leading jobs are being done by some of the mods
