There's a guy on the Wycombe board (L1), Ron is his name, I think he's out in France he runs a weekly football virtual betting league. I don't bet, simply because I don't like losing money, but I always participate in his virtual bets (when I remember).
He allocates you a £1,000 a month, which must all be spent by the end of month, he gives you the teams betting odds of the L1 only games you can bet on, and your return (winnings) is based on the odds.
