As far as Madness goes, since you're on that roster, you can talk to Morgan Eldred or Paul Heyman about possibly being added to the card. We often times try to book everyone on the active roster but sometimes the GMs will narrow it down to who replied to the booking thread in the booking area. I can't speak for them, but it's possible they had a full card and didn't see your name in the booking thread.

Also, there's an open battle royal that anyone can RP for on Warfare.
