Handle Private League disputes
League disputes aren't fun, so knowing how to resolve them if they happen is important.
Yahoo doesn't interfere in any way when it comes to Private Leagues including issues with a Private League commissioner. Using the league's message boards or directly emailing the commissioner is the best way to address any problems.
For a Fantasy Sports experience without a commissioner try a Public League. Yahoo acts as commissioner in Public Leagues where Fair Play and Sportsmanship guidelines are enforced.
