If you haven't signed up yet, click on 'Register' and select 'Join Team' during the registration process, or from your dashboard once you've finished registering.
If you are already registered, go to your dashboard and select 'Create/Join Team'.
Then, go to 'Join a team' and search for your team name to join!
Another way to do this it to get your Team Captain to share the link to your Team's page. Head to it while logged in and click 'Join Us' and you're in!
