Within a season you can create groups to organize teams. Most create a group for each age group or division. When a coach creates a team they will be asked what group the team show be added to.
To create a Group, first select the Season you want to add the group(s) to.
Then click Groups in the upper right hand corner.
Click Create New Group
Now enter in the Group Name, Gender, and Age Range. Once that info is entered hit Save.
