Ideally, you should know your Custom League commissioner either personally or through participation in a previous Yahoo! Sports Fantasy league. Custom Leagues consisting of friends, family, or co-workers are ideal because managers tend to be in close contact and usually have similar activity and ability levels.

When joining a Custom League, please remember that the commissioner of the league has full authority over all league matters. Among the tools and authorities available to Custom League commissioners are:

• Ability to lock managers from posting on the message board, adding/dropping players, trading, making roster moves or changing their team name.
• Ability to remove posts from the message board.
• Ability to change rosters for those teams that have enabled commissioner control.

The commissioner may exercise any of these authorities at any time and without explanation to league members.

Yahoo! Sports will not act as a go-between with commissioners and managers in any way. All Custom League matters must be addressed to the commissioner.
