Looks like the team leaders can initiate a team battle between teams.
Press the link and if you are not the team leader you will not see team battle but if you are a team leader you will see beside settings the button team battle.
Now it's only a question of convincing 5 team members to be on line at the same time. They will then be representing that team.
You also need to know in advance the two teams that will be paired together and agree to a time & date.
You need at least 2 teams to generate a tournament.
You can't post in the forums yet. Play some games!
