To join or create a team in Mayor Match, you must reach level 21.

By selecting the "Team" menu once you reach level 21, you may quickly join a team! You may either use the search button to locate and join teams from there, or you can discover teams to join.

If there are openings on a team, click the "Join" option to apply. If a team is "closed," you must wait for the Team Leader's permission before joining.
