Please note that each group may contain several classes.

Each group is displayed in a separate window in TournamentService. (for team events: two windows) .

To switch group (i.e. select and work with another group), press Ctrl-Tab or select from the Groups menu.

Groups are created as needed in the tournament options screen.
