they charge 33$ for a new league site and 22$ to renew once next madden drops. Subscription runs from one madden to the next. To me well worth it . It has forums, blogs , transaction logs, scores,stats,league leader stats, schedules, owners contact info page, standings, power rankings, and a awesome player search and player compare page.
