How about people post when they achieve a new, unheard of status tier for the first time. That way, when the inevitable deterioration of UGS or 3P status kicks in, we'll have a clear indication as to when that tier has "jumped the shark," so to speak.
So, please note, my post titled "I just made UIS! Kiss my F-riding lily-white behind!" will be coming post haste.
