Hi! I have a query about registration, hopefully someone on here can help... Is there a certain period of time after registering a player before they can be completely unregistered? For the Area, we will be registering a percussionist currently playing in an unregistered band. However, in the summer, his usual band will be playing in a contest where no registered players are permitted. Could he be registered and unregistered within the space of 3 months? Can't find anything about it in the rules, and it's better to be safe than sorry! Thanks!
