That's the Category for Accepted. In the past, there was a difference between Accepted and Soldiers - they had different people above them in the chain of command and different options for where they could end up (Ajah or Company). Once integration came in, there was no need to have separate Accepted and Soldier Categories, so everyone was moved into a new Category http://library.tarvalon.net/index.php?title=Category:TarValon.Net_Accepted_and_Soldiers
Yup, I switched all Accepted and Soldiers into the new category yesterday (that took a while). Novices and Recruits need to be done still, as far as I know.
