can not increase waiver claims once the season starts
Our Commissioner changed the # of Waiver claims 3 weeks after the season started. That is not what I signed up for. This is cheating.

Yahoo doesn't interfere in any way when it comes to Private Leagues including issues with a Private League commissioner. Using League Chat 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.
