Set the rules before inviting players
Finalize the format, roster, scoring, draft, waivers, trades, schedule and playoffs before the league becomes active.
Use clear invitations
Players should know the sport, format, draft date, league size and any important custom settings before joining.
Avoid mid-season surprises
Do not change competitive rules casually after games begin. When a correction is required, document what changed and why.
Handle scoring issues with evidence
Check the league's actual scoring settings, source stats, correction history and provider status before changing a score.
Communicate important changes
Draft changes, scoring corrections, playoff updates and other material decisions should be clearly announced to league members.
Delegate without giving away ownership
Co-commissioners may help operate assigned leagues, but billing, plan ownership and financial controls remain with the primary owner.
Use official rules as the source of truth
League-specific settings and the published sport/game rules should control decisions rather than informal chat or assumptions.
