This Fantasy Betting is a just-for-fun way to manage betting on your site. Every user who logs in gets a set amount of 'dollars' or 'quid' or 'bangles' (you decide the currency) then have an opportunity to place a fun wager on items of your choice. When you're ready to announce the winner, all users are sent an email asking them to re-visit your site to claim their 'winnings. ' Thus this becomes a great way to get repeat customers.
