How do I JOIN the team?

After logging in, click Find Teams to search through teams you would like to join.

Once you found the team you'd like to join, send the request by clicking "Join the Team" button.
If you are a captain, you may not see the button. Currently join the team is available only if you are a team member. If you delete a team from the clash tab in LoL client, you can be a teamplayer.
(The ability to invite captain to his teammates is coming soon)
Your request will be checked by the team captain, and the captain may accept your request and add you in LoL Client.
You MUST join the team in the client in order to participate in Clash. Make sure the captain has invited you!
