Wild cards are now supported. In this tournament the top two teams from each group move up to the quarter finals, along with the next two teams with the best records. The Wild card group shows these teams after the other groups are complete. In this example, Scotland and Wales are those teams.
Both Scotland and Wales are matched against other Group B teams in this example. Usually tournament organizers will switch the matches so that the wild card teams play teams from other groups. This kind of change requires "edit" privileges, which is more restricted than "report" privileges.
