Benefit system

Benefit system adds a points-based rewards system to Moodle. Users earn points for completing activities and courses; points are configurable per activity and in course settings. They can exchange points for digital rewards (files or voucher codes) or physical rewards. Admins create and manage rewards, set costs and stock, and add redemption instructions. Users view their balance, exchange points, and track their rewards and history. An optional block shows avatar, name, points, and links to rewards pages; admins get a purchase history link.
