When a new team match starts, all members of that group/team will receive a message.
You can click through to view and then join the match. Or, you can go to your group’s homepage and then use the "Team Matches" link under the Group Menu when you will see a list of any active/available Team Matches.
If there are any available matches then you can click the "view" link and you will be brought to the specific Team Match page. There you will see a link to join the Team Match if there is still space available for more players.
