Maybe one way to "pay it forward" is to share not just credits / clubs / balls, but also advice on how to play a particular shot / how to improve etc.
While some are happy to scorn the better players here, there are others of us that are thankful to receive whatever advice there is ....... free to give and potentially of hege benifit to the recipient!
I kinow that whenever I play blitz / stroke with anybody I am always pretty chatty and look for whatever help is going!
