Click the "Registration" tab at the top of the screen.
For the league you want to register for, click "Register" and select the fee type in the drop-down.
If the league you are looking for doesn't show up automatically, you can search the league by clicking the "All Events" button.
Select your preferred division, IF required, (which most leagues are), then click the "Application Form" button to start the registration for that individual team.
Repeat step 4 for all teams you need to register in this league.
