To join you need to click on Register - under User Details, then choose Nickname and then enter email and password details. Then choose your team.
When that's done make sure you are logged in with your own Nickname and password and click on View Team - under Team Details.
You should then be able to click on Join to join a mini-league. Enter the league number as 2535 and the password as Bigbrother.
