Just to tickle your imagination, I could invision the subforum. There would be multiple threads, each of the threads would be for a certain staff position. For example, there could be a thread for Clan Squad, have a description of what they do and list the current and previous members of that specific group. There could be a mega-thread for all the old staff positions that are no longer available. The pro of having a subforum for this would be that it would be easier to categorize and log who received what position. The current staff list just needs someone that is willing to update it.
But as the others pointed out, it's just not worth pursuing.
