Every other forum is well under control, and not too many mods have left... c_leks went missing, true... and we're all very worried! But DS was never away. Several global moderators are around on the forums for a few hours a day each, and Gilbert and Fuzzpilz are around a lot too. The problem is just that the competitions forum is a very different thing, with so many competitions that need to be locked on a regular basis, most of which will be uninteresting to any one of us, nobody is reading them to lock them once voting is finished. If anyone wants that job, PM CJ, sure.
"There are several people with global moderator status that, for one reason or another, have not been taking an active role in the forum's upkeep" - who? I almost never post an "I moderated this!" notice on threads, I just move, merge, delete etc. So it might not be obvious when mods do things. But in the general forums abusive threads are locked pretty quickly, by whichever moderator sees them, and the tech forums are kept tidy by the tech forum mods, you do a fine job in critics, and darth's moderation of the GiP forum is legendary!
