This way, one could quickly
- determine whether an open game has still an open spot for yet another team
(i.e. "3/2:2:2" could mean that all three teams are fixed, with one player missing from each team, or it could mean that one entire team slot is still open; similarly with "3/3:3", etc.) - select or avoid certain teams (maybe because one has already played against them, etc.)
- see if my own team looks for another team member to join
