When a junior player starts with the club they are added as an unregistered member (they don't have their own login).
A parent(s) is added to the club as a registered member with the Parent role of their child(ren).
The parent(s) have access to manage their child's membership information, payments and schedule through the Parent member role.

Once the junior member is old enough to take responsibility to manage their own account (this often occurs at 16 or when they start to play senior hockey),
[b]the parent needs to add the juniors email address to their account.

The junior can then use their email address to log into their account and they the junior member is now directly responsible for managing their Pitchero account.

The parent(s) can still retain the Parent role of their child(ren) and see their schedule and complete payments for their child(ren), however, the parent(s) cannot see/update the child's membership information and roles or the child's messages.
