So, as I've been going through sign in sheets and waivers I've notice something us experienced players have been failing on.
Often it appears when a new player arrives and they are naturally unused to the way we do things they will sign a waiver but not sign the sign in sheet. Thus they're short a credit or more. Now they might not think this is much as new as they are but a day might come when they really want that credit. So we experienced players need to make sure they know about the sign in sheet and how to use it. I know monotonous but it's only polite. And remember, helping the newer and younger players is always a good sign to those who hand out rewards.
