All Custom League commissioners have the ability to edit the rosters or results associated with any team in his or her league. By joining a Custom League, you agree to give the commissioner of that league permission to modify your roster, lineup, or past results at any time without notification or explanation.
As a commissioner, you can edit another team's roster by going to your Commissioner Tools page and choosing the "Edit Rosters" option. Once there, select the team you wish to alter and the type of transaction from the pull-down boxes. You will then be presented with options that will allow you to make the desired move(s).
Since you can only control one team at a time, you will need to return to this page and follow the same procedure each time you wish to control another team.
The commissioner may also use the "Edit Team Points" option to change the fantasy point total (score) associated with any team from any completed week of the season. This feature may be used to make any adjustments to scoring based on offline league rules not supported automatically by the Yahoo! scoring system.
