The FA laws state:

"Under 7's or Under 8's are not permitted to play in leagues where results are collected or published or winner trophies are presented, this is deemed to be detrimental to the development of the player and the game and will not be sanctioned."

The Sports Organiser web display sytem can be used to follow this ruling as the web display export feature allows you to set options on the league details screen to ensure that the league table and match results are not exported with the fixture details.
