Enrollment lists have been published for everything besides Nationals. Will include San Antonio's list as courtesy but I don't plan on editing changes on all threads so I'm not going to overextend for all the others. Seems like most pre-contest discussion for BOA events happens on HornRank's forums anyhow, and this place really lights up more on contest day.
