Why would there be? If you knew about all the staff positions before, they were eliminated/morphed into other staff positions because there were too many to manage and inconvenient.
Ninjas, TSAs, GMs, MS, Smods, Admins, CMods, and ItemForgers are all the community needs to work properly.
If I missed any, sorry.
Just look at the "All staff, past and present" Thread. All the Ex positions are pretty astounding.
What's your reason behind thinking this? Has anything been shown that might lead you to believe a certain staff position is going to be removed or morphed to make a new one? If anything like this has happened, you would need to tell us. We can't really answer you if you just randomly thought they would be making a new staff position.
