Hat League (friends or pairs)
Set up a hat league where players can sign up individually, as pairs or they can indicate who they want to play with in the sign-up form.
Ensure that the sign-up form keeps it open to people who just want to play with their friends, but also to people who don't mind who they play with.
Target Audience: All player levels, particularly new players
Benefits: Players can sign up with their friends and can be moved in pairs or always keeping two together in a group.
Disadvantages: Teams might be a bit more unequal or harder to organize throughout the season to keep players together.
