I believe it only the 6 A grade Super league Franchises are allowed to do it.
There was a healthy debate about it with JD as the Pride in the Red and Green meeting came to it's conclusion last week.
It will only happen if we allow it to happen, if clubs and fans in the championships could somehow get together as one and stand up to the RFL and say we aren't standing for this the way you treat us isn't good enough.
