In most leagues the teams don't change much from year to year so, rather than start from scratch and enter all the team names and team players, we've provided a method to copy the data from year to year. Hopefully this will save some work.
To access this, click on the copy icon by the league you want to copy in the List of Leagues and confirm that you wish to continue. It'll take a moment or two and then you'll see your new league listed at the bottom of the list. You still have some work to do, though.
Once this is done you'll be able to carry on just like the previous season.
