Another well thought out suggestion here, and to be honest, I've not actually felt the impact of the global moderators on this forum like I feel it on btt, admin seems to be the only one who is already all around handling all the stuffs that goes on and around on this forum, from moving topics, or deleting the ones that need to be deleted, to banning users who break forum rules, to wiping users karma who are seen to be abusing the karma system, to flagging accounts that engages in any form of malicious activities and so on and so on, admin does everything, and some time ago, I've actually wondered within myself what really are the task given to global moderators to handle on the forum? Or is the "Global moderator" badge the carry around nothing but a decoration on their profile?
We want admin to live long, and to actualize this, the work load on him need to be significantly reduced, just like hugeblack have pointed out, admin should distribute some this tasks to the global moderators, if there aren't enough global mods, I can volunteer myself to become one, distributing the tasks will help the admin focus more on what's really important on the improvements the forum needs, this is lead to a faster improvements and growth of the forum..
